Adding OutputCache to an ASP.NET WebForm crashes my site :(
- by Pure.Krome
Hi folks,
When I add either one of these ...
<%@ OutputCache Duration="600" Location="Any" VaryByParam="*" %>
or
<%@ OutputCache CacheProfile="CmsArticlesListOrItem" %>
(.. and this into the web.config file...)
<caching>
<outputCacheSettings>
<outputCacheProfiles>
<add name="CmsArticlesListOrItem" duration="600" varyByParam="*" />
</outputCacheProfiles>
</outputCacheSettings>
<sqlCacheDependency ........ ></sqlCacheDependency
</caching>
my page/site crashes with the following error:-
Source: System.Web

Ok .. so for some reason, the OutputCache wants a folder/file to be there? Well, i've had this site live for around 3 years and i'm pretty sure that the folders \Controls and \Controls\InfoAdvice doesn't exist on my production server. On my localhost, it sure does .. and contains a large list of ascx controls.
But they don't exist on my live server.
So ... what is going on here?
Can anyone please help?
Oh :) Before someone suggests I create those two folders and even stick a random file in those folders .. and have some random text in those random files .. i've done that and it doesn't seem to work, still :(
Please Help !
