Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Ed Eddington]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Firefox is not returning a cookie set by a server with multiple sub-domains
(a.b.c.com) or using IP for domain. Cookies work normally for single sub-domain. 

I could not set a cookie for such a server using these methods:
1. Explicit (domain='a.b.c.com' or domain='.a.b.c.com')
2. Default (no domain specified)
3. IP-based (domain='12.3.45.67')

Mozilla 1.7.5 did not exhibit this problem.

Reproducible: Always

Steps to Reproduce:
1. Send Set-Cookie header from server with domain like "a.b.c.com"
2. List cookies sent back from Firefox on next request
3. Cookie is not sent


Expected Results:  
Cookies should be stored and sent to servers with multiple sub-domains.

After doing 'Remove All Cookies', the cookie started being set correctly. I
turned on cookie logging, but have since been unable to reproduce the problem. I
had multiple cookies set for varying domains which may have been a factor.

Incidentally, the Web Developer toolbar (extension) *does* fail to show cookies
with domains like a.b.c.com in 'View Cookie Information'. But, the cookie log
shows that the cookies are accepted and sent properly, and Firefox shows them
within Tools-Options.

If I can reproduce the problem, I will pass along details.
