mod_proxy not passing through all Set-Cookie fields

           Summary: mod_proxy not passing through all Set-Cookie fields
           Product: Apache httpd-1.3
           Version: 1.3.24
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: ITS@uk.radan.com


I updated our proxy server from 1.3.19 to 1.3.23, and some of our intranet 
applications failed at that point.  However, this problem only affects clients 
with Netscape 4.x or IE - Netscape 6 users do not appear to see the problem.

Following a serial of network packet traces, the error has been narrowed down 
to the newer proxy server failing to pass through all the Set-Cookie fields 
returned from the server.  Attached are the traces of the request and response 
between client and proxy, and between proxy and destination web server:

---------------
Client to proxy server POST request:

---------------
Web server response back to proxy:

HTTP/1.1 200 OK
Date: Tue, 09 Apr 2002 13:44:45 GMT
Server: Apache/1.3.22 (Win32) PHP/4.0.6

---------------
Proxy server response back to client:

HTTP/1.1 200 OK
Date: Tue, 09 Apr 2002 13:41:24 GMT
Server: Apache/1.3.22 (Win32) PHP/4.0.6
Content-Type: text/html
Set-Cookie: vk=9f59f63d439c751a995b1bc37691be38; path=/

---------------
Note that in the proxy-client response there is no entry for the
Set-Cookie: sid=3782; path=/
entry.

This works fine with 1.3.19, but fails with both 1.3.23 and 1.3.24 servers.
httpd.conf file for proxy section is identical between all three versions of 
server.  All three versions have been taking straight from source and compiled 
with no extra modules on Solaris 7, running on Solaris 7 server.  Destination 
web server is apache 1.3.22 with PHP4.0.6 unchanged between all three proxy 
server versions.
