The number of client requests that were eligible for processing by the accelerator cache. Only simple GET requests are processed by the accelerator cache. The accelerator cache does not process requests that explicitly disable caching, for example, requests sent when a user clicks Reload in the browser and requests that include a query string, that is, requests for URLs that include a ? character.
To maximize the number of acceleratable requests, structure your web sites to use static files when possible and avoid using query strings in requests for static files.
