How to stop chrome from caching REST response from WebApi?

Question

I am using ASP.NET WebApi and have the following code to stop caching in everything:

public override System.Threading.Tasks.Task Execu         


        

Answer 1

The answer is that Chrome does not like "Expires:Mon, 01 Jan 0001 00:00:00 GMT" (a fake date, basically).

I changed my date to be what they use in their Google API, and it worked:

Cache-Control:no-store, must-revalidate, no-cache, max-age=0
Content-Length:1897
Content-Type:application/json; charset=utf-8
Date:Fri, 19 Jul 2013 20:51:49 GMT
Expires:Mon, 01 Jan 1990 00:00:00 GMT
Pragma:no-cache
Server:Microsoft-IIS/8.0

So, for anyone else who comes across this problem, make sure you set your Expires date to this arbitrary date!
