The names of the variables are following an ancient de facto standard and are built up as "[protocol]_proxy" (note the lower casing). Which makes the variable 'http_proxy' checked for a name of a proxy to use when the input URL is HTTP. Following the same rule, the variable named 'ftp_proxy' is checked for FTP URLs. Again, the proxies are always HTTP proxies, the different names of the variables simply allows different HTTP proxies to be used.</SPAN></FONT></P><P style="margin: 0.0px 0.0px 14.0px 0.0px"><FONT class="Apple-style-span" face="Arial" size="4"><SPAN class="Apple-style-span" style="font-size: 14.4px;">The proxy environment variable contents should be in the format "[protocol://][user:password@]machine[:port]".

'all_proxy' is what sets proxy for any URL in case the protocol specific variable wasn't set, and 'no_proxy' defines a list of hosts that should not use a proxy even though a variable may say so. If 'no_proxy' is a plain asterisk ("*") it matches all hosts.</SPAN></FONT></P><P style="margin: 0.0px 0.0px 14.0px 0.0px"><FONT class="Apple-style-span" face="Arial" size="4"><SPAN class="Apple-style-span" style="font-size: 14.4px;">To explicitly disable libcurl's checking for and using the proxy environment variables, set the proxy name to "" - an empty string - with CURLOPT_PROXY.</SPAN></FONT></P><P style="margin: 0.0px 0.0px 14.0px 0.0px"><FONT class="Apple-style-span" face="Arial" size="4"><SPAN class="Apple-style-span" style="font-size: 14.4px;"><BR class="khtml-block-placeholder"></SPAN></FONT></P><P style="margin: 0.0px 0.0px 14.0px 0.0px"><FONT class="Apple-style-span" face="Arial" size="4"><SPAN class="Apple-style-span" style="font-size: 14.4px;"><BR class="khtml-block-placeholder"></SPAN></FONT></P><A href="http://curl.haxx.se/libcurl/c/libcurl-tutorial.html">http://curl.haxx.se/libcurl/c/libcurl-tutorial.html</A><BR><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV></BODY></HTML>
