.NET Forum / ASP.NET / Caching / July 2008Cache directives ignored by Firefox
Hi, I add the following to my aspx page code-behind (3.5). I've tried it in several of the page events: Response.Cache.SetNoStore() Response.Cache.SetNoServerCaching() Response.Cache.SetAllowResponseInBrowserHistory(False) Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.Cache.SetExpires(New Date(1900, 1, 1)) Response.Cache.SetLastModified(New Date(1900, 1, 1)) My page has a wizard, and the browser (Firefox 3), still caches the page and I can use the browser back button to go to the previous wizard step, which I don;t want. I want it to expire (in IE it does.) ANy ideas? Thanks Paul Hi Paul, From your description, you're encountering some problem with disable client-side browser cache in firefox browser. Regarding on this, I've also performed some test on my side. Generally, the following code should be necessary to disable client-side cache: ======================= Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Response.Cache.SetAllowResponseInBrowserHistory(False) Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.Cache.SetNoStore() Response.Expires = 0 Response.Write("<br/>" & DateTime.Now.ToLongTimeString()) End Sub ============================== And my local tests showed that it works corretly for IE7 and firefox 2.0. However, for firefox 3.0, it does not work. I think it is due to the implemenation of the firefox 3. BTW, the cache control http header is a advisory info and the actual implemation is not mandatory and depend on the browser, so I suggest you also try submit this issue to firefox community to see whether this is an by design behavior.

It's only working with IE7. Please let me know the way you got it working with Firefox 2.0 in your local testing? Thanks! Som. Thanks for your input Som, Yes, based on my test, it will display a message box in Firefox2 f or the expireing info. Actually, when I choose to continue, the page will become expire or I can choose not to. I assume this is the expect expire behavior in Firefox as I haven't found the exact same behavior(like the one in IE). Anyway, in firefox3 , even this behavior is not available.

You can override this behavior by calling the SetAllowResponseInBrowserHistory method with the allow parameter set to true." So, "Response.Cache.SetAllowResponseInBrowserHistory(False)" is really unnecessary. > ======================= > Protected Sub Page_Load(ByVal sender As Object, ByVal e As [quoted text clipped - 8 lines] > End Sub > ============================== Free MagazinesGet these publications absolutely FREE for up to 12 months.
