reCAPTCHA through a proxy server

[jetpac]

Is it possible to run reCAPTCHA through a proxy server? I use GoDaddy
hosting, and they won't let the script open a socket to reCAPTCHA's
servers as it is now.


This help article on GoDaddy's site has a simple way of getting a
page, but I don't know how to adapt this to make it work with the
reCAPTCHA script.

Doesn't anybody know? Is this even possible?

You need to make slight modifications to the PHP code to use a proxy, have it say:

POST http://api-verify.recaptcha.net/verify HTTP/1.0

when making the request and make the fsock_open call point to godaddy's proxy. We'd be happy to take a patch that make proxies a configuration option.

Hello,
For the life of me I cannot get this to work with Go Daddy hosting. I
will be the first to admit that I am a extreme novice when it comes to
php.
I uploaded the pages that come with the recaptcha-php-1.10.zip file.
When I browse to the example-captcha.php it does not give me a false
response when what I type in is false. I do know that Go Daddy proxy
is http://proxy.shr.secureserver.net:3128
I do not know, however where to make modifications in recaptchalib.php
to make it point there...
Would you be able to help me out?
Thank You,
Jason

Where EXACTLY do we make the code modification? I can see several
places in the recapchalib.php file that have the word false? I don't
want to mess up the code and I'm no genius. could you give some exact
parameters to place the change?

I came up with this patch just now (sorry for repost- first time I
posted it contained a paste-o)
