This bug has been taken from bug 99638,

I suffer from this problem CONSISTENTLY on my personal web site. I log in to my
site and maintain a session ID in the query string.  My site uses frames and
TARGET="_top_" to manipulate the window.  If I click on such a link that takes
over the window and click back, I lose my login query string.  Additionally, If
I clicked that link from a non-default page in a frame (ie. not the page
specified in the frameset), it does not return to that page either, but only the
default page. Additionally when I log in, I cannot click back through pages in a
frame...  Perhaps I should create a login on my site for you to tinker with:

Click the Links link. Click Back. It works.

Click on the Family link and enter the following login info:


Now click one of the Links icon on the left. Try clicking back. For me it
doesn't work.

Notice the query string. On the Links page, pick Slashdot. Click Back. Notice
the query string is gone and the Links page is also gone (it's back to the
default page).

This is on Mandrake Linux 8.0, Mozilla 0.9.5 (build 2001101202).

I have always had touch and go luck with navigating frames on my site using
back.  0.9.5 introduced the elimination of the querystring.

Initial Patch to docshell
This is what's going on here. 

After you fill in the login and password, the family page is loaded in the right
frame, but before it could be displayed, the _top is replaced by a new page with
session-id etc.... , which looks identical to  the previous page. This
replacement of the _top, after a series of subframe navigations was confusing
session history. 

The patch attached makes sure that replacement loads in the _top as well as in
subframes are clearly identified in session history which will enable smooth
behavior of the back and forward button.

Re-nominating for  0.9.4 branch. we need this patch in the 9.4 branch to take
care of some serious siebel problems(see bug 128379) I have a tree with this
patch ready to go. This has baked  in the trunk for almost 3 months. I would
like to check this into 0.9.4 branch today.  Sun has also verified that this
patch fixes their problem.
