Wildcard subdmoains

Hi all,

just an sanity check from my part: AFAIK it should be possible in apache to
set a subdomain as wildcard domain. So, in a virtualhost:

ServerAlias the_target.example.com *.example.com

And as long as an A record is set:
*.example.com A 1.2.3.4

Every <random_string>.example.com should arriev at the virualhost that is
configured, am I right? So I could define a subdomain in this particular
vhost, and it;s not required to be the 'main' domain?

I'd say this is right, unfoturnatly I'm not entirely sure as the only DNS
records I can manipulate (and unfortunatly no vhosts manually) are with
said hoster.

Am I wrong (ohoh, apologies are in order..) or not? Am I missing something?
Could it be because of further requiremens that I missed?

Does anyone per chance know wether the fact I/the hoster uses Plesk makes
any difference?

Keep me sane, say I'm right :-)

To the best of my knowledge ServerAliad DOES NOT take a wildcard ...

AFAIK a name based vhost needs all valid alliasses spelled out.
IP based has a chance to work using some rewriting...

I am trying to use module_rewrite to solve your problem, but not success
yet. I am newbie to apache too.

Maybe following will give you some hints

#try to response http://AAA.example.com/test.htm with /AAA/test.htm
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com$
RewriteRule ^/(.*)$ /$1/$2

An untested thought ...
RewriteRule ^/(.*)$ /%1/$1 [QSA,PT]

Still, AFAIK only functional for those FQDN specified with servername or
serveralias witin a common vhost.

Well, the .htaccess rewrite is the simple bit. Let's say I have a subdomain
subs.example.com, to which I wish to direct all 'unknown' subdomains:

RewriteCond %{HTTP_HOST} ^subs\.example\.com
RewriteRule ^(.*)$ /choose.php?foo=$1 [QSA,L]

RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?request=%1&foo=$1 [QSA,L]

RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ $1?request=%i [QSA,L]

I tested this. It does works!

use the following configuration:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.aray\.com$
RewriteRule ^/(.*)$ /%1/$1 [QSA,PT]

Use IE request this url http://a.aray.com/file/not/exsits.htm, following log
will apears in access_log
192.168.255.254 - - [15/Dec/2006:09:18:37 +0800] "GET /a.htm HTTP/1.1" 304 -

Use Ie request this url http://a.aray.com/file/not/exsits.htm, folling log
will apears

in access_log:
192.168.255.254 - - [15/Dec/2006:09:22:14 +0800] "GET /file/not/exsits.htm
HTTP/1.1" 404 219

in error_log:

Offcourse it does, however, it was not my problem :-).

The point was to even arive at 'specific_subdomain.example.com' from
'random_subdomain.example.com'

Maybe, you can use module_rewrite to use files in "specific directory"
to response the request wich has header "specific_subdomain.example.com".
and all other request with header 'random_subdomain.example.com' not
configured explicit use a file "invalid_domain.htm".

Then, 'specific_subdomain.example.com' is arive from
'random_subdomain.example.com'

Oops, my English is poor, I try hard to read your words, may misunderstand
you.

Nonono. For the files in the specific directory to work, first we have to
arrive THERE. That's the problem. Everything beyond that is a piece of cake
:-).

To illustrate, say I have in the document root of specific_sub.example.com
this file:

----index.html-----
<html>
<head>
<title>Wildcards</title>
</head>
<body>
<p>This is specific_sub.example.com, but you may have reached it
under another name</p>
</body>
</html>
--------------------

Now what I want is that EVERY not specifically configured subdomain arrives
here, and will show the same file. How I will distinguish how they got
there is of no importance. This has to work, everything further is peanuts.
