If your PPM deployment includes an external Web server, then you must use the following optimizations:
Enable dynamic content compression on the Web server
For example, on Apache, enable the mod_deflate module. On Microsoft Internet Information Services (IIS), enable native compression. For detailed information, see the Installation and Administration Guide.
Some Web servers disable keepalive. For example, Apache mod_ssl (HTTPS) disables keepalive for Microsoft Internet Explorer by default. If you are running Apache and mod_ssl to provide HTTPS support, you must make sure that keepalive is enabled.
Disable cache-control header interference
For example, on Apache, enable mod_expires.
