Interesting OutputCache expiration problem

Hi,

I have a user control MyControl.ascx which appears on various pages in
my ASP .NET 2.0 application. I have setup partial-page caching using
OutputCache directive so that this control gets cached on each page.
However, there is one page Update.aspx which contains the control and
has features that update the DB entries that determine the output of
the control.

I have set SqlDependency so that the control's cache is expired when
the table is updated. But on this page, if I update the DB, the cache
does not expire immediately, and hence when the page is returned back
to the user the control still shows the older values. The cache is not
expired immediately because the SqlDependency is only periodically
refreshed to check if there is a change. Since the DB is updated on
postback in an event handler, the postbacked page is returned with the
older cached control.

Is there a way to expire the control's cache immediately so that the
control on this page renders with the updated values?

Thanks,
Yash

Question: If I have an ASP.NET User Control which defines/exposes a property that the page can use to specify a mode or data subset for the control to use, is there a way to tell the @OutputCache directive to vary its cache based on that property value? I.e., I have: <my:control runat="server" id="mcOne" Flag="One" /> <my:control runat="server" id="mcTwo" Flag="Two" />

The following piece of code, when on a heavily loaded server (more than 50 ASP.NET pages, most using outputcache with varybyparam, lots of users), will only cache the string - the output is not cached, as if the outputcache is ignored. There is available RAM on the server. Other pages are cached as expected. On the development environment and on a test server, it works fine. Are there any limitations to the .NET caching, apart from RAM...

If I set the outputcache like this.. <%@ OutputCache Duration="900" VaryByParam="none" %> on a server on the east coast. Will someone who hits the site on the west coast get three hours added to the cache expiration? it mentions at msdn that Response.Cache.SetExpires should follow UTC and any HTTP1.1 docs that you read on w3c will say that UTC is the only accepted format.

Hi, I get the following error, I thought at random intervals. Then I realized, that this happens around the time tha page outputCache is set to expire. So I disabled the page output cache and the problem went away. I put in the outputcache back and the problem is back. I am using forms authentication... and asp.net 2.0. Have you seen this problem before... any help is deeply appreciated.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
