cUrl version

Hello Win2k, Apache 2.0, PHP5 I need to make an http request from behind an ISA proxy server. I am trying to use cURL for this, as it seems to offer the most configurable options with relation to a proxy server. This is the code I am using: $ch=curl_init(); curl_setopt ($ch, CURLOPT_URL, 'http://www.google.com/'); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch,CURLOPT_HTTP_VERSION,'CURL_HTTP_VERSION_1_1'); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); curl_setopt($ch,CURLOPT_PROXY,'10.0.0.8:8080'); curl_setopt($ch,CURLOPT_PROXYUSERPWD,'abc:123'); $ret = curl_exec($ch); It is failing as I am getting a 407 from the proxy server. This is apparently a known issue: https://sourceforge.net/tracker/?func=detail&atid=100976&aid=1188280&group_i d=976 I believe that this is fixed in the latest version of curl, which is 7.14.0. However, as far as I know, I would need a new version of php_curl.dll in order to use this. I do not understand how to build this myself, or even what I would need in order to do this, and am not sure that I have the necessary software in any case. Are there any tutorials out there on how to do this? Thanks in advance Mark
