When displaying a database driven product page, I cache the page using:
<%@ OutputCache Duration="86400 " VaryByParam="Pr oductID" %>
which works fine UNLESS I change the pricing or description for that page in the
database.
Then, I need to clear the cache (either for that specific productID- or for the
aspx page and all the ProductID's it displays).
How can I clear the cache under program control?

Yes, I realize that - but that is not a good solution.
As the data on the page is tied to a database, I need a way to automatically
clear this cache when the database has changed.
By automatically, I mean using code, not modifying a page by hand in an editor -
or even changing the timestamp on the file (which requires certain permissions)
Somewhere inside of .NET, this cache lives - and there must be a way to clear
it..

What you're talking about is database dependency.... Asp.net does not support this natively unless your db is file based (it supports file dedendencies). But it can be done. Refer to: http://www.gotdotnet.com/team/rhoward/

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...

sorry about the previous post, by mistake not completed.
i have an asp.net page with the line
<%@ OutputCache Duration="30" VaryByParam="none" %>
but when i make requests to the page with different parameters, i get different result,
but i tries to check if i set the VaryByParam to none there should be the same output for different parameters, so why does it not work?

I had an aspx page with output caching turned on. Then I wanted to do some
other stuff and I commented it out like:
<!--
<%@ OutputCache Duration="1800" VaryByParam="t" %>
-->
The IDE correctly shows this as a green comment...but don't be fooled. .NET
still processes and caches the output. In my case, the ClientID values
started being duplicated for a DataList object.

Hi,
I have some controls with these:
<%@ OutputCache Duration="500" Shared="true" VaryByParam="None" %>
However, I need that under certain user action, specifically, changing
a value on a dropdownlist with auto-postback, the cache for the control
be cleaned and the content regenerated.
Is there a way to do this ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
