Cache settings

prx-cache

Cache Enabled

Switches the cache on and off. If disabled, each web page is always retrieved directly from the Internet.

Cache Directory

The directory in which the cache will be stored.

Cache size

The amount of disk space that will be used by the proxy cache. When deciding about the size, consider the number of your users, the traffic they generate, etc. If you have enough free space you may set a larger cache. The maximum size is 2000 megabytes.

Continue Aborted

If checked, the Proxy server will always finish downloading an object from the Internet, even if the user's browser aborts the request (the user hits the stop button, or follows a link to another page without waiting for the current page to be downloaded in full). Subsequent visits to the same page are thus much faster.

Keep Aborted

This instructs the WinRoute's Proxy server to cache even incomplete objects (web pages, images). This provides for at least partial speed-up when the web page is revisited. If "Continue Aborted" is checked, the setting of "Keep Aborted" is ignored.

Cache FTP directory only

When browsing FTP servers, use this option to only cache the directory listings. If you wish to cache the files downloaded from a FTP servers as well, switch this option off. The decision whether a particular file will be cached also depends on its size, please refer to "Max. Object Size" bellow.

Use server supplied Time-to-Live

Time-to-Live is the period of time after which a particular web page is considered obsolete and its contents must be re-fetched from its server. This option instructs the WinRoute's Proxy server to obey the Time-to-Live (TTL) that comes with the individual pages. If a page has no TTL, the Proxy's default TTL is used.

Ignore server Cache-Control directive

If the contents of a web page changes very often, the author of the page may decide to set the "no-cache" directive for it. This is a very useful feature, however some web sites use the directive much too often, sometimes for all their pages, effectively eliminating the purpose of proxy servers. If you need to protect against such behavior enable this option.

Max. Object Size

The maximum size of objects to be stored in the cache. Larger objects will be passed to user's browser, but not recorded in the cache. Usually you do not need to cache large objects (like program archive files), since you do not download them repeatedly.
