Redirects, Set-Cookie: headers, and HTTP/1.1 mod_proxy
I have patched up our apache 1.3.20 server with the current
source/patch at
http://cvs.apache.org/viewcvs.cgi/httpd-proxy/module-1.0/ with the
effect that the it now returns HTTP/1.1 responses instead of HTTP/1.0.
This server is used as a reverse proxy server that fetches content
from two different real servers using ProxyPass and RewriteRule [P]
directives.
However, after applying the patch the reverse proxy seems to eat some
Set-Cookie: headers set by my real servers in server redirect
responses.
Here is an example: I have the reverse proxy listening at
xxx.yyy.zzz.www and the real server is listening on 127.0.0.1, both
are running on the same machine.
If I do a request directly to the real server, I get
-----------------start-------------------
bash-2.04$ telnet 127.0.0.1 80
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
GET /agent/moblogin?USERNAME=<user>&PASSWORD=<passwd>&LOCALE=<locale>
HTTP/1.1
Host: myhost.mydomain.com

Set-Cookie: moblocale=en_US;path=/

<HEAD><TITLE>302 Moved Temporarily</TITLE></HEAD>

</BODY>
Connection closed by foreign host.
-----------------stop-------------------
However, when I do the same request to the reverse proxy, the first
Set-Cookie: header disappears:
-----------------start-------------------
bash-2.04$ telnet xxx.yyy.zzz.www 80
Trying xxx.yyy.zzz.www...
Connected to xxx.yyy.zzz.www.

Why doesn't the proxy let the "Set-Cookie: moblocale=en_US;path=/"
header through? It just disappears!
What happens here?
