The Caching Proxy is configured as a caching proxy server when installed.
Use the Proxy Performance configuration page to fine-tune your proxy
server's performance in the following areas.
Running the server strictly as a proxy server, rather than as a content
host as well, will improve its performance.
You can improve performance for clients by allowing open, persistent
connections with them. This practice decreases lag time that otherwise
would be spent establishing a new connection. However, allowing persistent
connections increases network bandwidth usage and requires dedicated server
threads. If your server frequently has most or all of its configured threads
in use, consider not allowing persistent connections.
You can enable the proxy to consult the SOCKS configuration file to
determine whether or not to connect through the SOCKS server.
To improve performance, do not send HTTP/1.0 requests downstream
unless necessary. This feature should only be enabled if you must connect
to Web servers that do not support HTTP/1.1, for example, if you use
proxy chaining to go to a parent proxy that does not support HTTP/1.1.
You can specify URLs for which the server appends carriage return
and line feed control characters to the end of the body of a Post request.
To improve performance, only specify CRLF for URLs that have a known problem
processing Post requests.
And lastly, if you have a Web site that uses relative paths in its links
to an FTP server, you can specify that the proxy server use relative paths
instead of the absolute path default.
