OutputCache is sending wrong Vary header when the call hits the cache

Question

I have an action method that I want to cache:

[OutputCache(Duration=60*5, Location=OutputCacheLocation.Any, VaryByCustom=\"index\")]
public ActionResult Index()
         


        

Answer 1

Sort of wrestling with something similar myself. Have you tried in the web.config to the setting omitVaryStar=true
