Title: HTTP Proxy for Outgoing Requests

Besides serving HTTP requests from clients, for certain operations, a Traction server may also be issuing requests to other remote servers. Retrieving images to be attached to articles, fetching newsfeeds for use with the FeedReader component, and retrieving remote images to be embedded in exported content all potentially require a Traction server to make HTTP requests to remote hosts. In many environments, it will be necessary or useful to route such requests through an HTTP proxy server. Starting with version 3.7, your Traction server can be configured to use an HTTP proxy for its outbound HTTP requests.

The configuration interface for HTTP proxying is located on the Server Setup - Network tab:

You can simply specify the address and port for the proxy server, or for more elaborate configurations, you can also specify the username/password credentials to be used to authenticate with the proxy.

Be sure that if you plan to use the credentials for the proxy, that the "Use Credentials for Proxy" checkbox is checked; and likewise, if you want Traction to use NTLM authentication with the proxy server, that the "Use NTLM Authentication When Possible" checkbox is checked. Also, be sure to check the "Use HTTP Proxy for outgoing requests" checkbox to enable HTTP proxy usage; even if you've entered the address and port of the server, it will not be used until you check that box.
