Re: Proxy support for HTTPAPI

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

Hi Sebastian,

I really appreciate all of the work you put into this.

Also, I'm very pleased with the unified diff! I work with FreeBSD all 
the time, and am very familiar with this format... it's so much nicer 
this way than when people send me entire copies of the source member. 
So thank you very much for using diff/patch!

I've created a beta version of HTTPAPI 1.18 that contains your proxy 
code.  I can't test it myself, as I do not have access to a proxy 
server, but hopefully other poeple will try it out.  The files to 
install can be found here:

SAVF:  http://www.scottklement.com/httpapi/beta/httpapi.savf
XML:   http://www.scottklement.com/httpapi/beta/httpapi.xml
ZIP:   http://www.scottklement.com/httpapi/beta/httpapi.zip

Thanks for your help, Sebastian!
