784428 - First two characters of domain name are repeated under specific scenarios

Status: VERIFIED DUPLICATE of bug 775072

(Firefox :: Untriaged, defect)

Description

[seth.goldstein]

User Agent: Mozilla/5.0 (Windows NT 5.2; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build ID: 20120713134347

Steps to reproduce:

We ran into an issue with our web site where the first two characters of the domain name are duplicated.  The steps taken were:

1) Entered gosavo.com in the address bar and hit enter
2) Browser is redirected to: https://www.gosavo.com/Login.aspx?ReturnUrl=%2f [this is fine and not the issue]
3) Entered https://www.gosavo.com/Login.aspx in the address bar and hit enter
4) Browser ends up on https://www.gogosavo.com/Login.aspx [this is the issue]

You will notice that in step 4, the "go" is duplicated at the beginning of the domain

If I run Fiddler, I see no redirects.  Fiddler tells me that the browser goes straight to "https://www.gogosavo.com/Login.aspx".  It does not tell me that it goes to "https://www.gosavo.com/Login.aspx" and is redirected.

We have removed all rewrite rules we have in IIS to eliminate that as a possibility.

Of my development team, only 2 people have been able to reproduce the issue.  Most people are able to navigate to "https://www.gosavo.com/Login.aspx" without issue.

We also tried Firefox ESR and did not have an issue
We also tried IE 9 and Chrome 21.0.1180.79 m and did not have an issue

We have currently only seen the issue with Firefox 14.0.1 and only on two separate computers.

The randomness of the issue makes me think that there may be some odd bug in Firefox 14.0.1.


Actual results:

Browser ends up on https://www.gogosavo.com/Login.aspx


Expected results:

Browser ends up on https://www.gosavo.com/Login.aspx

Do you also cleared the disk cache on the affected systems as redirects can be cached.

ctrl+shift+del , everthing and only cache checked....

We had cleared cache before and the problem persisted.

Just now, I just tried clearing everything (cache, cookies, history, etc) and unfortunately I can no longer reproduce the problem.  I am going to keep investigating and let you know what I find.

[seth.goldstein]

So I just tried clearing everything on a different machine and the problem still persists there.  So on one machine, it started working.  On the other, it still fails.  Both Firefox 14.0.1.  But the issue historically is very random.  The one that started working might be entirely coincidental.

Is the same happening if you paste the URL in the URL bar ?
Could you attach a http log (via the "add an attachment" link above) if you still get the issue with a pasted URL.

https://developer.mozilla.org/en-US/docs/HTTP_Logging
use "set NSPR_LOG_MODULES=timestamp,nsHttp:5,nsHostResolver:5"

This should show if this issue is something that we get from the network or from the URL bar.

Maybe bug 775072

Thanks for pointing out 775072.  The led me to:

https://bugzilla.mozilla.org/show_bug.cgi?id=770644

770644 looks absolutely identical to my bug with the first two characters being duplicated.

I have no concern with my bug being closed as a duplicate of 770644.  Please do so if you concur.

Marking as duplicate as per last comment. Thanks!

I expected that this is a dupe of bug 775072 and that's why i asked if it still happens if you paste the link. Another test would be to use a link.
