Is there a way to cache a user requested data depending upon the user/connection. My situation is that I display the data returned from the WCF in ASP.NET Gridview using paging. The gridview paging displays only 10 items at a time. Whenever the next page is clicked, the service is getting called again (which takes time). After each call the WCF connection is closed. Is there a way to fix this issue? I read upon WCF ASP.NET caching mechanism that caches functions call data and it expires after a certain time. My main thing, is per user/call caching like return 10 items at a time without calling the long running function again for each 10 sets of data. Is there a way to do?
Basically call the function the first time and get 100 items, and return it 10 at a time, without ever running the function again (which gets 100 items)?
I believe that the ASP.NET Gridview always does a postback which result in function call everytime a user changes page. But I maybe proven wrong by someone.
That being said, this may not be the best solution for you. But you could avoid using ASP.NET Gridview in your scenario. When you run a WCF call and return 100 items, you keep them on client side as a JSON file stored in memory, then use jQuery or some other form of javascript to enable users to go through pages without making another function call.

This may prove useful to you to help you do paging on client-side without having multiple repeated call to the server
