Hi Nick,
Thanks for the help!
Sorry for the abbreviated configuration. Here is my mod_proxy configuration in its entirety (only the hostnames in the URLs are changed). Note that I also moved the ProxyPass outside of the <Location> section, at your suggestion (before that, I had each ProxyPass inside the <Location> for its respective path, omitting the path argument on ProxyPass accordingly). Unfortunately that rearrangement didn't fix the situation.
ProxyRequests Off
ProxyPass /abc http://gdccideas.chn.hp.com/cgi-bin
ProxyPass /def http://gdccideas.chn.hp.com/cgi-bin
<Location /abc>
ProxyPassReverse http://<target-hostname>/cgi-bin
</Location>
<Location /def>
ProxyPassReverse http://<target-hostname>/cgi-bin
</Location>
Note also that on the <target-hostname> there is a CGI script, test.pl, which just redirects to http://<target-hostname>/cgi-bin/end.pl.
Now, the persistent problem is that when I make the following request to the proxy in my browser:
https://<proxy-hostname>/def/test.pl
(yes, the proxy is SSL-enabled but the target is not) I get the following redirect from the proxy:
Location: https://<proxy-hostname>/abc/end.pl
Notice how a request into the /def location ended-up getting redirected into the /abc location. That's the problem. Conversely, requests into /abc/test.pl get redirected to /abc/end.pl as they should.
Interestingly, if I reverse the 2 <Location> sections, it is the opposite behavior -- requests into either location for test.pl then redirect to /def/end.pl. In other words, it seems to be the first ProxyPassReverse listed in the configuration which takes effect, regardless of the fact that each should be scoped just to a <Location>.
It seems the same problem as you discussed back in February 2005 (see http://tech.groups.yahoo.com/group/new-httpd/message/52311 and follow the link to Neil Hillard's problem report contained therein).
I am using Apache 2.0.59.
Please advise, and thanks very much in advance!
