Question

I have an action that returns a view with a master page with a logon user control at the top. When I set outputcache, it caches the entire output including the current user, so everybody would see whoever was the last person to hit the page to refresh the cache as the current user. Is there a way to prevent the master page from being included in the cache?

I am using the following code:

[OutputCache(Duration=3000, VaryByParam={params})]  
public ActionResult {actionName}({params})  
{  
    {codeGoesHere}  
}

There was a concept of “donut caching” (excluding parts of a page from the output cache) but it didn’t made it in asp.net MVC 1. For solution to your problem you can try this workaround.
