Hi,
I am about to modify Apache with some custom logging for GET/POST
requests (and more). It is for the purpose of research. If possible, I
would like to get some guidance in how to implement my ideas. I will
explain...
Every GET/POST request to Apache will carry a request identifier.
Adding the

Yes, just about anything can be done in an
Apache module. Based on your other questions,
it sounds like you need a thorough exposition
of the Apache API and probably the HTTP protocol,
so I'd suggets your next step is to study some
good documenta

Thanks for your comments.
Until I get the book, can you tell if a module's hook function can
execute in the same thread as the CGI application that serves the
request?
Also, I am unable to find the apache2 API for building modules. I
found some documentation for developers on the apache2 website,

In ap_hook_fixups, is it possible to get the thread/process ID of the
CGI application serving the request? Moreover, is th

As another poster said, a standard CGI
script runs in a different processes and you
can't generally muck with the address space
of that process. To effect that script, what
you can do is change it's inputs and it's
outputs. Your module can add, remove, or
alter the query string, path inf
