Hi
Using MVC 1.0
How can i cache a page but not a user control on it.
lets say i have a tag cloud on my master page, tag cloud being a user control that i want refreshed only every x minutes.
do i need to do [Donut caching][1]?
or has it made it to MVC 1.0 ?
can it be done in client browser or only server caching ?

You have to do Donut caching on the server side. It is possible to do it on the client browser, but you would have to make a AJAX request after the fact, which is not really optimal. StackOverflow actually uses a form of this for their own tag cloud.
Yes, you have to use "post cache substitution" (also known as "donut caching"). ASP.NET automatically turns server-only caching when using "post cache substitution". Also consider using custom HtmlHelper extension method instead of UserControl (it's more ASP.NET MVC - like). There are some limitations in using "donut caching" on ASP.NET MVC. Maybe you shoud look at this question.
