Update the HTTP Cache Content 

Use

Quite often files that have been cached change. Therefore, the content of the cache must be updated by the system so that the appropriate version of the requested resource is returned to the client. To do this, you have to set a timeout, after which the system checks for newer versions of the files that are stored in the cache.

You may choose not to set such a timeout. In this case, you have to do some manual work to ensure that the cache does not contain irrelevant content when a resource changes. You must clear the content of the HTTP cache, either using the CLEAR_HTTP_CACHEshell command, or using the Visual Administrator. It guarantees that the next time a user requests the updated resource, the newest version of it is stored into the cache.

Prerequisites

You have to make sure that you have enabled caching on your HTTP Provider Service.
