How to specify HTTP expiration header? (ASP.NET MVC+IIS)
- by Marek
I am already using output caching in my ASP.NET MVC application.
Page speed tells me to specify HTTP cache expiration for css and images in the response header.
I know that the Response object contains some properties that control cache expiration. I know that these properties can be used to control HTTP caching for response that I am serving from my code:
Response.Expires
Response.ExpiresAbsolute
Response.CacheControl
or alternatively
Response.AddHeader("Expires", "Thu, 01 Dec 1994 16:00:00 GMT");
The question is how do I set the Expires header for resources that are served automatically, e.g. images, css and such?
