UserControl OutputCache and VaryByParam not working with postback!!
Don't know if anyone has come across this before. But if you have a usercontrol that uses VaryByParam and you have it on a page and do a postback you will get the wrong cache item. Use the below test bed to see what I mean, this is following to my post for help on the asp.net forums, I then found this post which showed me it is an issue, following this I think I came up with a solution. That is to add a hidden field to my page with the name MenuID and populate that. Now on postback it seems to work fine, as VaryByParam="MenuID" seems to read the form var MenuID and gets the correct value hence fixing caching.
