430077 - pages are cached even when no-cache is set

Status: RESOLVED DUPLICATE of bug 202896

(Core :: Networking: Cache, defect)

Description

[Adam McNeely]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; TRPIT; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1)
Build Identifier: 2.0.0.14

If you log into yahoo mail, then click logout, then click back it will display the main yahoo mail page.  It should not be caching and should display the login page.  It seems that Cache-Control, pragma, or expires are broken in firefox 2.0.0.14.  

Reproducible: Always

Steps to Reproduce:
1.  log into yahoo mail (mail.yahoo.com)
2.  log out
3.  click back button.  
Actual Results:  
browser displays the main mail page, not the login screen.

Expected Results:  
In previous versions of firefox and IE it will display the login screen and not cache the non-cacheable content.

You must disable firebug and any other add-ons for this to occur.

I think you have to use no-store rather than no-cache to kill the back button.  In what version of Firefox did you see it "work"?

I thought I could get this to work in 2.0.0.12 but it turned out I had firebug turned on, which "fixes" the problem.

no-store doesn't work as a meta tag.  It only works as an http header.  See bug 202896.
