Newbie: Page level caching in ASP.NET

[Navin Mishra]

Hi,

How could Page level caching be implemented in ASP.NET ? My ASP.NET page
takes some query arguments and I want page level cache to last for the
lifetime of the page generated using the passed arguments only. If different
arguments are passed, I want new page level cache for the new page. Is it as
simple as adding page level variables ? Note page may query data
asynchronously using AJAX also. Does it change things ?

Thanks and regards

Navin

Ajax shouldn't screw around with anything.

To cache different versions based on querystring values, use the VaryByParam
attribute of the OutputCache control

<%@ OutputCache Duration="3600" VaryByParam="id" %>

assuming "id" is the querystring you want to create a different cache on.

Take a look at:

Thanks. My qyery string is long passing a bunch of arguments. Would it work
for a combination of query string arguments ? Is there a limit ? I also
wanted simple caching while generated page is active and, to use the cache,
when an action is performed on the page. When page is destroyed, I want to
clear THAT page level cache. Would simple page level variables do that are
garbage collected when Page object is destroyed after ASP.NET page request
completes ?

Thanks again and regards
