问题 To disable caching files from ajax requests, you can use jQuery's $.ajaxSetup({ cache: false }); But how does jQuery do this? I know jQuery is a javascript library, so whatever can be done with jQuery can be done with plain javascript. So my question is: What is the javascript code that jQuery uses under the hood to turn off ajax file caching ? 回答1: This is the source of the cache if ( s.cache === false ) { s.url = rts.test( cacheURL ) ? // If there is already a '_' parameter, set its value

Once there is a lot of traffic from our app (MVC site) the memory usage of IIS goes through the roof very quickly. Ideally we want to be able to release the memory that these DataTables consume once requested from the Cache. The code of the Controller is something along the lines of Using (DataTable dt = DataTable) { DataTable dt = Cache.GetObject(objectID); //perform some

问题 I'm currently developing a large site that handles user registrations. A social networking website for argument's sake. However, I've noticed a lag in page loads and deciphered that it is the creation of objects on pages that's slowing things down. For example, I have a Member object, that when instantiated with an ID passed as a construct parameter, it queries the database for that members' row in the members database table. Not bad, but this is created each time a page is loaded; and called
