If you have done any decent amount of work with the ASP.NET MVC platform, you have probably run into the following problem. You have a page where you want to update data on the server without a postback and so you whip out some fancy Javascript to send a request to the server. What happens is the response you get back is a success, and the data is updated, but subsequent requests don’t seem to be updated. This is most noticeable with partial views and content views called via the infamous “$.ajax” call. What you forgot was to make sure the browser isn’t caching the result:

1

HttpContext.Response.AddHeader("cache-control", "no-cache");

Note that if you have already hit the particular view and it is cached, you can generally clear the cache by navigating to the URI of the view manually and hitting refresh.
