Remove output cache on a user control

[whatsthehampton]

Hi,

Been reading all day but just cannot find a solution to this one...

I have a userControl (header.ascx) which has an <ASP:Image> in it

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

m is a querystring values indicating the users username

I want to output cache this userControl for some time; but if the user uploads a new image - how do I remove the cache for this page and reset the cache after the upload?

I programmatically change the name of the image to stop that caching.

Cheers,
Jeff
