This section provides details on the LoadMaster UI options available in System Configuration > Miscellaneous Options > AFE Configuration.

Maximum Cache Size

This defines how much memory can be utilized by the cache in megabytes. The Maximum Cache Size defines how much of the main memory should be assigned to the cache. It can never be more than one fifth of the total memory of the machine. Assigning more memory for the cache will reduce the amount of memory available for connections and persist entries. In a system that is correctly configured, there should be enough memory for a full cache and all connections that the system is expected to handle. If this is not the case, the system could run out of memory.

Cache Virtual Hosts

This option is enabled by default. When this option is disabled, the cache presumes there is only one virtual host supported on the Real Server. Enabling this option allows the cache to support multiple virtual hosts which have different content. If a request is cached for one Virtual Service, it will not be cached a second time if the request is sent to another Virtual Service. This is based on the host header of the request.

File extensions that should not be cached

The File extensions that should not be cached field and the label below it specifies a list of file types that should not be cached.

The default extensions that are not cached are .aspx, .jsp, .php, and .shtml. You can delete these from the "no cache" list by selecting them and clicking Delete.

You can add other file extensions to the File extensions that should not be cached field.

Items are held in the cache for 15 minutes (or until the cache is flushed by refreshing the page (for example, by pressing Ctrl + F5 on your keyboard)).
