Caching Proxy is sensitive to changes to TCP/IP configurations. Lowering the TCP/IP values on any operating system might cause the proxy server to perform in an unexpected manner. More specifically, if the TCP/IP values are set too low, connections might be reset by clients that connect to the proxy server or by origin servers to which the proxy connect. This is especially true for clients that connect to the proxy server through a low bandwidth connection (56700 bps or lower). If TCP/IP parameters must be lowered, proceed with caution.
