Use an HTTP Proxy
This option enables SourceOffSite Clients to work through a client-side proxy server.
Please note: SourceOffSite will only work with proxy servers that enable CONNECTS.
To configure SourceOffSite to connect through a proxy server, check the Use an HTTP Proxy option. When this option is checked, the HTTP Proxy section will be enabled. Enter the IP address of the proxy server in the Proxy Server text box and enter the proxy port in the Proxy Port text box, then press OK.
