Httpd Redirectiion Question ?

Hi,
I am new to httpd and apache.

I just wanted to know...

1) Whenever the httpd gets an html page/data. I want the entire
data/page
to be redirected to my function (ie my code).

How do i do it ?.

2) if it is a get/post message i want to give some message back to
the
"process" that sent the message (data).

How do i do it ?


What i want to do is "my code should process the message". once i
process
the message. i want "my code" to give the message back to httpd
which
in turn sends the reply to the request.

I want to program (ie the function to be written in C) as i am
profiecient
with that language.


I just wanted to know, if this can be done in apache/httpd.

I dont want to modify the source code of httpd/apache.

Can i do it without modifying the source code ?.


I know perl/PHP are used for the above purpose ?.
But I dont know how to do it.
I am a novice. I have gone through httpd.conf and already confused
with it.


Kindly, Advice me. It would be very helpful if you give an detailed
answer
with some examples.

Surfing the Net also did not help as the information available could
not be understood by me.


Please Advice.


Thank you for your time.


Regards,

mitra

The configuration directive for Apache is ScriptAlias (there are other
ways to enable a directory to contain scripts, see the Apache
documentation for details), for example

ScriptAlias /cgi-bin /home/www/cgi-bin

The Web server passes information about the request and POST data in a
stanardized way, and expects a response in a certain format.

See the Common Gateway Interface (CGI) specification at
http://hoohoo.ncsa.uiuc.edu/cgi/ for details on what you get and how to
return a response.
