Add web proxy support to httppoller

[Kevin312]

I have a need to run different web scenarios through different explicit HTTP proxy servers, so I can compare the performance of the proxies.

Our HTTP proxy requires authentication, and listens on TCP port 3128.

I've attached a patch to "httptest.c" which enables the above, this was written for v1.6.5 but can easily be forward ported to the latest version of Zabbix.

To use a non-authenticating proxy, you just include the name/IP and port in the variables section, like this:

{proxy}=10.231.91.8:3128

Or to use a proxy that requires authentication, you can include a username, password, and optional authentication type.

that's a neat feature, could you report it on the ZBXNEXT tracker and attach the patch ? thanks

edit : oh, and please create unified diff - you can produce it with 'svn diff'

Added to v1.8.1

I used this for version 1.8.1 and it works well.

The first time I applied the patch it puts the second lot of code in the wrong place.

In v1.8.1 testhttp.c it inserted the code in between these lines:

while((row=DBfetch(result)) && !err_str)
{

I restored the code and manually inserted it about 6 lines earlier so it was before "DBselect" block of code. That is about line 342. The first block of code went in at line 268 as per the patch.

Thanks for posting this code.

Can't get it to work in 1.8.4. The httptest.c file is totally different in 1.8.4
