Simple API for HTTP GET?

[Bryan Field-Elliot <br...@netmeme.org>]

We are building a module which, among other things, needs to do a simple
HTTP GET (or HTTPS GET) from another website. Operationally this will be
very similar to what mod_proxy does, though our module serves a
completely different purpose.

My question is, in the Apache 2.x codebase, is there a simple API call,
in any of the utility files, which can make this easier for us? 

e.g. an API call such as: "char* http_get(char* url)", which could be
invoked from any module...

Thank you,

Bryan

Hi,

I have asked similar question before and looking for solution sticked with
Apache 2.x codebase only.  Some replied to take a look at mod_proxy_http and
mod_include module as they do the exact thing.  However, it is complicated
and hard to understand up to my knowledge about Apache internal.

I agree that these HTTP/HTTPS GET API are common in module writing and
should provide handy APIs for module developer.  It should be glad if
someone can give more details about the solution.

I recommend that you use Serf:
http://svn.webdav.org/repos/projects/serf/trunk/

*cough* Someone still needs to make a website for Serf, but as a library 
it works quite nicely.

For an example of using serf inside a module, checkout mod_serf, which 
does reverse proxying:
http://people.apache.org/~pquerna/serf-stuff/mod_serf.c

Another option is libcurl:
http://curl.haxx.se/libcurl/

The curl_easy api is quite easy. If you just want simple GETs, it might 
be the smallest lines of code to implement.
