Weird problem with httpd skipping the start of files.

I'm new to running Apache.

I just installed 2.0.49 on Win XP Pro (using msi) along with the
latest mod_perl binary (ppm). I start it up, I load the default
index.html.en page from the Apache distribution htdocs page. So
far so good. Then I click on the "documentation" link from that
page which leads to the "manual" directory which is at the same
level as htdocs. Everything Apache serves from that directory
has the first 3500-3600 characters lopped off the front of the file
on the way to my browser. I see the file several lines in. This
was confirmed when I looked at document source from the broswer and
the actual file with a text editor. Some things show the tail end
of the previous HTML construct that got cut off in the middle. I
can't explain it. There's no errors in the error log and the access
log looks fine too. Has anyone seen this? What did I do wrong? I
can't seem to find anything about this with Google or looking through
the Apache web site. Nothing in the httpd.conf file seems to cover
something like this from what I can tell. The problem doesn't seem
to be browser related as it happens with both Firefox and IE6.

I tried inserting a bunch of characters at the start of one file
and I was able to get enough in for Apache to serve the whole of
the original file to the browser (minus my added characters). It's
bizarre.

I've gathered some more information. This problem shows up in
other directories as well. It seems to affect most, but not all
files. I can't see a difference between the files that are affected
and the ones that are.

I ran the Live HTTP Headers extension with Firefox. Here's the
HTTP headers loading one of the pages that gets front of the file
cut off:

The file perf-tuning.html.en, is in fact, 52783 bytes long but a
few thousand bytes are missing from the front of the file by the
time Apache sends it to the browser. If I load the file directly
from the file system, it loads fine.

Here's my httpd.conf file. It was configured by the MSI
installer for local use only. The only change I've made is
to add the perl_module line and to cloak my email address
just before I post this message.

Please help.


#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs-2.0/> for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "C:/Program Files/Apache Group/Apache2" will be interpreted by the
# server as "C:/Program Files/Apache Group/Apache2/logs/foo.log".
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which Apache.exe is located
# will be used by default. It is recommended that you always supply
# an explicit drive letter in absolute paths, however, to avoid
# confusion.
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.0/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "C:/Program Files/Apache Group/Apache2"

#
# ScoreBoardFile: File used to store internal server process information.
# If unspecified (the default), the scoreboard will be stored in an
# anonymous shared memory segment, and will be unavailable to third-party
# applications.
# If specified, ensure that no two invocations of Apache share the same
# scoreboard file. The scoreboard file MUST BE STORED ON A LOCAL DISK.
#
#ScoreBoardFile logs/apache_runtime_status

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
#
PidFile logs/httpd.pid

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15

##
## Server-Pool Size Regulation (MPM specific)
##

# WinNT MPM
# ThreadsPerChild: constant number of worker threads in the server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_winnt.c>
ThreadsPerChild 250
MaxRequestsPerChild 0
</IfModule>

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 127.1.1.1:8080

# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.

# to be loaded here.

# ExtendedStatus controls whether Apache will generate "full" status
# information (ExtendedStatus On) or just basic information (ExtendedStatus
# Off) when the "server-status" handler is called. The default is Off.
#
#ExtendedStatus On

### Section 2: 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition. These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed. This address appears on some server-generated pages, such
# as error documents. e.g. admin@your-domain.com
#
ServerAdmin billdav@cox.nospam.net

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work. See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make
# redirections work in a sensible way.
#
ServerName 127.1.1.1:8080

#
# UseCanonicalName: Determines how Apache constructs self-referencing
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client. When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName Off

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "C:/Program Files/Apache Group/Apache2/htdocs"

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory />

AllowOverride None
</Directory>

#
# Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#

#
# This should be changed to whatever you set DocumentRoot to.
#

#
# Possible values for the Options directive are "None", "All",

#
# UserDir: The name of the directory that is appended onto a user's home
# directory if a ~user request is received. Be especially careful to use
# proper, forward slashes here. On Windows NT, "Personal/My Website"
# is a more appropriate choice.
#
UserDir "My Documents/My Website"

#
# Control access to UserDir directories. The following is an example
# for a site where these directories are restricted to read-only.

#
# DirectoryIndex: sets the file that Apache will serve if a directory

#
# The index.html.var file (a type-map) is used to deliver content-
# negotiated documents. The MultiViews Option can be used for the
# same purpose, but it is much slower.

#
# TypesConfig describes where the mime.types file (or equivalent) is
# to be found.
#
TypesConfig conf/mime.types

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plain

#
# The mod_mime_magic module allows the server to use various hints from the
# contents of the file itself to determine its type. The MIMEMagicFile
# directive tells the module where the hint definitions are located.
#
<IfModule mod_mime_magic.c>

#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups on

#
# EnableMMAP: Control whether memory-mapping is used to deliver
# files (assuming that the underlying OS supports it).
# The default is on; turn this off if you serve from NFS-mounted
# filesystems. On some systems, turning it off (regardless of
# filesystem) can improve performance; for details, please see
# http://httpd.apache.org/docs-2.0/mod...tml#enablemmap
#
#EnableMMAP off

#
# EnableSendfile: Control whether the sendfile kernel support is
# used to deliver files (assuming that the OS supports it).
# The default is on; turn this off if you serve from NFS-mounted
# filesystems. Please see
# http://httpd.apache.org/docs-2.0/mod...enablesendfile
#
#EnableSendfile off

#
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog logs/error.log

#
# LogLevel: Control the number of messages logged to the error.log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
#
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%{Referer}i -> %U" referer

# You need to enable mod_logio.c to use %I and %O
#LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio

#
# The location and format of the access logfile (Common Logfile Format).
# If you do not define any access logfiles within a <VirtualHost>
# container, they will be logged here. Contrariwise, if you *do*
# define per-<VirtualHost> access logfiles, transactions will be
# logged therein and *not* in this file.
#
CustomLog logs/access.log common

#
# If you would like to have agent and referer logfiles, uncomment the
# following directives.
#
#CustomLog logs/referer.log referer
#CustomLog logs/agent.log agent

#
# If you prefer a single logfile with access, agent, and referer information
# (Combined Logfile Format) you can use the following directive.
#
#CustomLog logs/access.log combined

#
# ServerTokens
# This directive configures what you return as the Server HTTP response
# Header. The default is 'Full' which sends information about the OS-Type
# and compiled in modules.
# Set to one of: Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
#
ServerTokens Full

#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory
# listings, mod_status and mod_info output etc., but not CGI generated

Your requested file and return file are different.

Turn off your manual alias, turn off your type-map,
then test to determine if manual files are served correctly
when the requested file is actually the returned file.

Is your browser XML enabled? Shouldn't be a problem for
your circumstances but some manual files are XML created.
Look at your perf-tuning source for an xml blurb, and note
the same file is available XML (.xml) created in your "misc"
directory storing your manual files.

Behavior will be different for various browsers. Additionally,
some browsers may not correctly recognize a double dot filename,
nor a file ending with a two letter country code.

Turn off your alias, type mapping, then access a simple .html
file and note results. If all loads correctly, then turn on
your alias and type features, and test again.

I tried requesting the .en file directly and had the same problem.

I believe I found the alias line:

AliasMatch ^/manual(?:/(?:de|en|fr|ja|ko|ru))?(/.*)?$ "C:/Program Files/Apache Group/Apache2/manual$1"

I tried commenting it out. I restarted apache and I still have
the same problem when going with the .en file. I had to move
the manual directory into htdocs so that apache could find it
without the alias. I'm not sure what you mean by type mapping.

I tried commenting out these:


<Files *.html>
SetHandler type-map
</Files>

and:

AddHandler type-map var

It had no effect.

I've tried it with both Firefox 0.8 and IE6 with all the latest
patches from Microsoft updates (6.0.2800.1106.xpsp2.030422-1633).
It misbehaves the same with both of them.

Would Firefox 0.8 really be one of those? I've been told that
it's the most standards compliant browser out there.

I tried a simple file like this:

foo.html:

<HTML>
<BODY>
<P>This is a simple file.</P>
</BODY>
</HTML>

That loaded fine from htdocs and htdocs/manual. It also loaded
fine from htdocs with the alias and type-map lines enabled and
manual directory put back where it was. I did not load from the
manual directory after that though:

That message makes no sense to me.

This seems very odd for a default installation.

Correct.

Check to be sure there are no other type map syntax
hidden somewhere; easy to miss.

This appears to be a type map error. I am not all that familiar
with how country code type mapping is handled; I do not use
country code files.

This " : " error suggests to me a number of processes take
place for the country code alias mapping.

Only suggestion I have is turn off all your type mapping syntax
and test with your simple html file you wrote. This will confirm
or eliminate a type mapping error or possible bug.

Reduce all "things" to the most simple configuration, this is,
turn off all modules which are not critical to basic operation.
Then test with your hand written html file. If successful, then
turn _one_ module back on, at a time until your error appears.
This "should" locate the problem source.

I have the same "misc" directory as you, but have all type
mapping turned off and have deleted all files with two
letter country code extensions. No problems. However I am
running a more stable 1.3.x version, which less buggy and
significantly more stable than your 2.x series version.

Strip your Apache down to bare bones, test, turn one feature
at time back on until the error appears. Once found, research
and read about the feature causing problems.

Stick with your simple html file you wrote, that is a
very good testing method.

I did a search for type-map in httpd.conf and those were the
only things I found.

That certainly seems to make sense.

I did turn it off (I think) but still had the problem.

I think I need to spend more time with the manual. I figured that
since I used a default MSI installation, that other people would
have run into this before me and someone would know what's wrong
and how to fix it.

Then it's not exactly the same then. All of the files without
country codes in my manual directory are just pointers to the
files with country codes. For example:

manual/misc/perf-tuning.html:

URI: perf-tuning.html.en
Content-Language: en
Content-type: text/html; charset=ISO-8859-1

That's it. The whole file. It's just a redirect. All the
information is in the language code files.

Here's another one:

manual/index.html:

URI: index.html.de
Content-Language: de
Content-type: text/html; charset=ISO-8859-1

URI: index.html.en
Content-Language: en
Content-type: text/html; charset=ISO-8859-1

URI: index.html.ja.jis
Content-Language: ja
Content-type: text/html; charset=ISO-2022-JP

URI: index.html.ko.euc-kr
Content-Language: ko
Content-type: text/html; charset=EUC-KR

URI: index.html.ru.koi8-r
Content-Language: ru
Content-type: text/html; charset=KOI8-R

And that's it. Loading index.html.en, either directly or by loading
this file cuts off the front 3500-3600 bytes of the file.

Maybe I should try the older version. I just want to set up
a local server so I can write/test some mod_perl stuff.

Hasn't apache 2 been around for years now? I remember someone
warning me off it at least 3 years ago. I was thinking it'd
be doing well by now.

I'm definitely going to have to spend more time with the manual
for that. It's hard to know what to disable.

The problem is, I want it to work with everything. I think I
need to be looking at directives related to type mapping in the
manual more closely. That appears to be at the core of the
problem.

Thanks for the help.

I finally found the solution to the problem:

http://www.apache.org/dist/httpd/binaries/win32/#xpbug

It's apparently a bug in XP and there are workarounds. A couple
of directives, an apache restart and a flush of browser cache and
I'm in business. Thanks to Purl Gurl for trying. The answer was
in the docs but unfortunatly I didn't think of the right search
terms. As near as I can tell, it wasn't the type mapping at all.
It was apparently the size of the files. Files larger than a
certain size ran into the problem.

I have read a lot of articles, recently, here and elsewhere
relating problems with graphic files not loading correctly.

Some are blaming Zone Alarm, others are blaming Norton AV,
yet others say it is some execute call thing, a few claim
this is related to the price of bananas.

Personally I believe Scotty has been drinking too much
Saurian brandy, of late, and Captain Kirk has become to
old and docile to attract green skinned slave girls
with exotic names, like Marta.

If you continue to have problems, upgrade to an Apache
1.3.x version, with the preferred version for Win32
being 1.3.27 version. Very stable, few bugs, fast and
efficient. I would run no other version.

I am pleased you solved your problem, and appreciate
your link to information. I am off to read and learn.

Hello Bill,

I was pulling my hair out over the same thing (WinXP, Apache 2.xx,
php)

I'm not sure if you ever found a solution, but I'll post this for
anyone else who might stumble onto this post.

From here: http://www.computing.net/windows2000...rum/58154.html

****************************
I had (note I said had) the same problem, it took me a week but I
finally corrected it. If you're running xp and have NTFS file system
do this:

EnableSendfile off

I also turned this off although I did this first and it didn't enable
the file send, but suggests turning off if using NFS:

EnableMMAP off

Hope this helps!
Feathers

I did this and it worked like a champ.
