How would you access the cache from a jQuery ajax call?

I’m using jquery to do some data verification and quick data access. I have a static web-method that jquery is calling via json to return a value. I don’t want to call to the database everytime so I’d like to cache the data I’m hitting, but I can’t determine how to call the asp.net cache from within javascript, or a static method.

I’d like to send the page object through to the static method, which would allow me to access page.cache, but don’t know how. Barring that, maybe a way to access the cache from javascript itself?

  1. System.Web.HttpContext.Current.Cache

    Cache is shared per app domain – not per Page. Page just has a convenience property of Page.Cache to get the current Cache, which means you can just do Cache[‘key’] from a method in a page.

    As you’ve noticed, if you’re in a static method – then you have no Page instance, and you have no Page.Cache property. So, you need to use HttpContext.Cache. But, wait – you have no HttpContext instance either! That’s ok, the currently executing instance is stored at the static property of HttpContext.Current.

    So – to answer your question – in a static method, use HttpContext.Current.Cache. BTW, you can also access the Request and Response properties from there.
