Note Submitter: mbabcock@fibrespeed.net ---- Proxy functions from the CURL docs: CURLOPT_PROXY If you need libcurl to use a http proxy to access the outside world, set the proxy string with this option. The parameter should be a char * to a zero terminated string. To specify port number in this string, append":[port]" to the end of the host name. The proxy string may be prefixed with "[proto­col]://" since any such prefix will be ignored. CURLOPT_PROXYPORT Set this long with this option to set the proxy port to use unless it is specified in the proxy string CURLOPT_PROXY. CURLOPT_HTTPPROXYTUNNEL Set the parameter to non-zero to get the library to tunnel all non-HTTP operations through the given HTTP proxy. Do note that there is a big difference to use a proxy and to tunnel through it. If you don't know what this means, you probably don't want this tunnel option. (Added in libcurl 7.3)
