cache cache

Cache control. Lets you selectively disable client-side caching (browser, proxy servers, network caching systems) and caching in the internal Platform Server cache.

cache= *cacheControl*

cache= *clientControl*, *serverControl*

on | off | validate
on | off
on | off

If only one cacheControl value is specified, it is applied to both client and server caches.

The ’ validate’ keyword allows updating server cache entries after texture or vignette files have changed, without having to wait for the cache entry to expire automatically. Client caching is not affected by this command.

If specified in a nested request, cache=on enables persistent, server-side caching of the image generated by the nested request. Take care that you enable caching for nested requests only when the same nested request is called repeatedly with the same parameters.

May occur anywhere in the request. Ignored when the request does not return a reply image. The property clientControl is ignored when client-side caching is disabled by the material catalog (if attribute::Expiration has a negative value). The property serverControl is ignored if server caching is disabled ( PlatformServer::cache.enable).
