need help with Tomcat-generated redirects
Hi,
I have some applications running under a Tomcat installation set up in this way:
[load balancer on port 80] ---> [Apache server on port 5001] --> [Tomcat server on port 7001]
One of the Tomcat applications sends a redirect to Apache because there is a <welcome-file> directive. However, the redirect that is sent says:
www.site.com:5001/foo/bar.jsp
instead of
www.site.com/foo/bar.jsp
On the Apache side, I already have ServerName set to www.site.com:80 to solve this problem for mod_rewrite. What is the corresponding directive for Tomcat?

Connector attribute proxyPort should fix the inclusion of the port
number in tomcat generated urls.

Ok, thanks for your advice, Bill - I'll see what we can do about building a more recent mod_jk to prop this environment up for now. We are using AJP/1.3 so I think that should be fairly safe.

Assuming that you are using the AJP13Interceptor, then updating the mod_jk
version should be enough. The problem is that mod_jk 1.2.6 doesn't respect
the UseCanonicalName directive and sends the actual port that Apache is
listening on.
If you are using the CoyoteConnector (which was released as an addon to
3.3.1a), then I think that the proxyPort directive will work. This
connector also ships with 3.3.2, which is a fairly painless upgrade (as
opposed to 5.5.x or 6.0.x).

Yes, the AJP/1.2 connector was deprecated even for 3.3.1a (except as a way
to shut Tomcat down :). To get this to work, you'll have to be using the
AJP/1.3 protocol.

I'm not laughing (at least I try to). Since I'm relatively sure about
the jk feature: what about updating to a recent jk version. 1.2.6 is
..., we are at 1.2.26.
I never worked with TC 3.3, but the docs tell us, that it allows an
AJP13 connector, so that one should be compatible with recent JK
versions. In case you are still using AJP12, that's not a safe bet to
use AJP12 with recent JK.
The docs look like the connector attributes we posted as an alternative
solution unfortunately don't exist for 3.3.

I'm using mod_jk 1.2.6 and Apache 2.0.59. UseCanonicalName is already on in the Apache server, and the ServerName is set to www.site.com:80 in the VirtualHost. I also tried to set ServerName globally and that didn't make a difference.
This allows mod_rewrite to send the correct port # in rewrites, but Tomcat doesn't seem to pick this up for some reason.
By the way, don't laugh, but this is a legacy Tomcat 3.3.1a application so I need something for that version of Tomcat.

How do you connect Apache to Tomcat?
If you are using mod_jk, the module gets the port it sends to Tomcat via
ap_get_server_port(), which in turn depends on UseCanonicalName. If this
is set to On, the port is also determined from the port in ServerName.
The AJP protocol then makes sure, that Tomcat thinks it's using the port
that mod_jk told Tomcat.
In case this doesn't work or you are using some other way to connect
Apache to Tomcat:
The connector element in server.xml knows about attributes proxyName,
proxyPort and scheme. See
http://tomcat.apache.org/tomcat-6.0-doc/config/http.html
