Help in Understanding Apache Filter

[Mansour <ms...@yahoo.com>]

Hi
I’m working in master project and I need to write an apache filter in this project.
 
I want to understand how to write a filter in apache, I read tens of tutorials and books and I did not find any thing simple and clear, I got confused!
 
For now I need a simple tutorial on how I can write a simple apache filter? Let say the filter is an output filter that will inject a text to the output. Also, I don’t prefer to use mod_perl in the filter.
 
How I can write this filter? How I can compile it? Is apxs will work to configure the filter?
 
Do you know a good tutorial that will help me in understanding how to write filter for apache? Or can any one help me with that?
 
I learned how to write a handler, but I didn't understand how I can make the filter work.
 
Thanks

have you also read throw the httpd manual?
http://httpd.apache.org/docs/2.2/filter.html

perhaps take a look at mod_substitute docu and its source:
http://httpd.apache.org/docs/2.2/mod/mod_substitute.html

maybe this docu is also helpful:
http://httpd.apache.org/docs/2.2/mod/mod_filter.html

two other small filter modules are in ./modules/experimental ...
