[Zope3-dev] Problems with Zope 3, Virtual Hosting (Apache) and Cookies

[Stephan Richter]

Hello everyone,

after a lot of fruitless hours, I finally figured out why setting cookies does 
not work when using Virtual Hosting with Apache. The problem is that when a 
response is returned to Apache, Apache combs through the headers and removes 
all "Set-Cookie" header entries except the last one, so that only one 
"Set-Cookie" header per Apache response is sent to the browser. I reread the 
corresponding RFC and verified that our generated Cookie Headers follow the 
standard. 

You can easily reproduce the bug by installing Apache and put Zope 3 behind 
it. Create a page that generates several cookies and execute it. Then observe 
the HTTP header you got back from Apache and you will notice that there is 
only one "Set-Cookie" entry.

Does anyone have a clue how to address this issue? BTW, I am using

Server version: Apache/1.3.23 (Unix)  (Red-Hat/Linux)
Server built:   Jun 19 2002 11:55:23

Regards,
Stephan
