random error when using page outputCache

[Nalaka]

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.

Default .aspx has.... <%@ OutputCache Duration="16000" Location="server"
VaryByParam="none" %>
Have not put any outputCache directive on master page....

Hello Nalaka,

As for this FileIOPermission security exception error with ASP.Net page
outputcache, I've also noticed your another previous thread below:

http://www.velocityreviews.com/forums/t361858-random-fileiopermission-error.
html

Is this problem still the same issue you encountered in that thread? If
so, as Walter has also mentioned, this is likely an environment specific
issue and he has also requested a simplified repro project. Have you been
able to create such a repro project? If so, you can send the project to me
so that we can perform some local test for on our environment. Please make
sure the project is a common and simplified one (based on IIS or vs 2005
test server). You can reach me through the email in my signature(remove
"online").

BTW, due to the nature of this issue's complexity, it may require some
advanced debugging to get the root cause and this is usually done through
the Product support team. Therefore, according to our newsgroup's support
limitation, it would be better for you to contact CSS for further
assistance if this issue is urgent for you.

Sincerely,

Steven Cheng
