RE: Cache directives ignored by Firefox
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.

Steven Cheng

RE: Cache directives ignored by Firefox
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.
