562736 - Request for relative uri after 302 redirect is occasionally relative to the original request

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[dan.rabe]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729)

We've observed this behavior sporadically in FF 3.5.8, 3.6.2 and 3.6.3 on both Windows XP and Mac OS X.

The user types in a URL like
http://myserver/ctx/svlt/doit
The server responds with a 302 redirect:
Location: http://myserver/ctx/blah/

The browser issues the GET to that url, and the server responds with an HTML page which includes relative references to CSS and JS files, such as:
<link rel="stylesheet" href="mystyle.css?123" type="text/css">
<script type="text/javascript" src="myscript.js?123"></script>

Almost all the time, FireFox does the right thing: it issues GET requests for
http://myserver/ctx/mystyle.css?123
and
http://myserver/ctx/myscript.js?123

However, once in a while, it makes the requests relative to the original request (the one that resulted in a redirect), not relative to the target of the redirect. In other words, it requests
http://myserver/ctx/svlt/mystyle.css?123
and
http://myserver/ctx/svlt/myscript.js?123


Reproducible: Sometimes

Steps to Reproduce:
Our app is not available to the internet at large, so I can describe this only in conceptual terms.
1. Create a setup as described in the bug report details. That is, a servlet that redirects to another url on the same server; the redirected-to url responds with HTML that includes relative references (we've seen the problem with CSS and JavaScript files; I don't know if the same problem would occur with image files).
2. Create a bookmark to the original url (the one that will result in a redirect). 
3. Navigate to the bookmarked url. After it redirects and you get the page displayed, click on the bookmark again. Repeat many times until you see the problem.

Reporter, are you still seeing this issue with Firefox 3.6.13 or later in safe mode? If not, please close. These links can help you in your testing.

You can also try to reproduce in Firefox 4 Beta 8 or later, there are many improvements in the new version, http://www.mozilla.com/en-US/firefox/all-beta.html

Haven't seen this recently, so hopefully it's fixed.
