44226 - Reload doesn't update session history.

Status: VERIFIED DUPLICATE of bug 40449

(Core :: DOM: Navigation, defect, P3)

Description

[kinmoz]

To see this bug, you need to load a URL that sends back different text content 
during every load.

Steps to reproduce:

1. Visit http://maug.mcom.com/cgi-bin/form.cgi
2. Note the date stamp on the page.
3. Press the reload button in the browser toolbar.
4. Note that the date stamp has updated to a more recent time.
5. Hit the browser back button.
6. Hit the browser forward button.
7. Notice that the page loaded displays the time stamp from the first load.

I first noticed this bug when loading bugzilla queries from my bookmarks. 
Everytime I loaded a query from a bookmark, I kept getting out of date results, 
no matter where in the session history chain I was. The only way to ensure that 
I was seeing up to date data was to hit the reload button.

Kin, I'm not sure I understand this right. Right now, when you hit relaod, 
docshell  just picks up the current uri  and initiates a normal load on it. 
Reloading by bypassing cache and/or proxy is not hooked up yet. What is the 
result you expect after step 4 and step 7.

I would expect to see the last version of the page I loaded.

Since pages output by CGI do not have a last-modified header, there is no way to 
cache them in a reasonable manner. If passing this CGI script the same 
parameters results in a different result each time, how and why are the results 
of each supposed to be stored in cache and written to the session history?

See also bug 46014, on keywords not loading in bugzilla pages: if you load a
bug, modify it and submit, then later go back and load the same bug, you'll see
the original page, not the latest version.
