262002 - mime type appears to be cached with page, but not updated even if server sends different mime type

Status: VERIFIED DUPLICATE of bug 198072

(Core :: Networking: Cache, defect)

Description

[fyodor]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

Admittedly not something that is likely to happen often, but if the server
changes mime type for a given page, only clearing the cache in Firefox will
enable the browser to "discover" that the mime type has changed for any cached
documents (i.e. reloading won't do the job).

Reproducible: Always
Steps to Reproduce:
1. Set default mime type to text/plain in Apache.
2. View a page that gets tagged with this default mime type (e.g. no extension,
depending on configuration)
3. Change default mime type to text/html (and restart Apache)
4. View same page.
Actual Results:  
Page still rendered with old mime type.

Expected Results:  
Page should be rendered with the mime type actually sent by the server.

If mime type is cached, it should also be checked (just as other content).

Probably a dup of bug 198072.

And oops, moved to wrong component.

yes, a duplicate. use shift+reload.

> If mime type is cached, it should also be checked (just as other content).

that checking happens by asking the server "has the content changed?". the
server answers "no it hasn't". so you get the behaviour you see.
