HTTP Content Caching

A Traffic Manager HTTP virtual server can detect commonly requested HTTP resources, and remember their content if it does not change each time it is requested. This capability is called “Content Caching”.

When the virtual server sees subsequent requests for the same resource, it can return the content for the resource directly from the local cache, rather than forwarding the request on to a (possibly overloaded) back-end server. This capability reduces the load on the back-end servers and improves the performance and capacity of your HTTP services.

Clicking the Content Caching link on the Virtual Servers > Edit page shows you the settings for content caching. You can enable the content caching capability, and specify how long various types of content are cached for. Content caching is only available for HTTP virtual servers, and for virtual servers accepting and decrypting HTTPS traffic.

Content Caching is described in detail in Content Caching.

HTTP Content Caching is not available on all Traffic Manager configurations. If required, it can be obtained via a software or license key upgrade.
