Sending a POST request and handling the response from a module

[David Wortham <dj...@gmail.com>]

Module Gurus,

My module does (among many other things) HTTP POSTs to another webserver.  I
was just told that I will have to be able to read (and deal with) data in
the response of a POST.  I believe I will only need to regurgitate the
results of the response (without the headers) into the module's/filter's
output.

My existing POST code was borrowed from ApacheBench (ab.c), which does not
appear to handle any of the response and is now much less useful to me.
Does anyone know of code that will allow me to both POST request and handle
the response data (and uses the APR libs)?

A quick search on Google Codesearch revealed that Nick (Kew) wrote a
HTTPClient.(c|h) library (used with mod_validator and possibly with
others).  Will this code do what I want?



Thanks,
David Wortham

Um, that's a quick&dirty hack, and likely to require significantly
more work to re-use an AN Other context.

If I were rewriting that now, I think I'd base it around a mod_proxy
subrequest instead.

While I really like Nick's response (regarding creating a subrequest through
mod_proxy), one of my supervisors doesn't like the fact that we require
mod_proxy to be installed for my module to work (took me a couple of
searches on some newsgroups to get it compiled/installed/activated myself).

I will look into Serf, but I'm not sure that I will like the results (seeing
that it is still in its infancy stages).

Thanks for the responses guys!

Regards,
Dave

http://code.google.com/p/serf/

might do that. Stumpled across it some days ago.
