iChain supports GZIP-compressed data between the browser and the proxy server. This additional support improves the overall performance of content delivery when the Web application has GZIP enabled.
The GZIP feature relies on the Web server to send GZIP-compressed data.
NOTE:Some Web servers, including Microsoft* Internet Information Services (IIS), do not respond with compressed (GZIP) data if a Via HTTP header is sent from a proxy to the Web server.
