Thanks a million Rainer, you got me over that hump! I have it working
now but have another question - When the response is generated for a
request, that used the alias in the URL, is there a way to keep the
client browser from displaying what the alias got mapped to?
Alias maps URIs to local file system directories.
JkMount maps URIs to remote back end requests.
You can not change JkMount forwarding using Alias (except that if you
have a comflict between Alias and JkMount only one of them wins).
As far as I understand you are not really trying to map requests to
the local web server file system, but instead want to forward to a
Tomcat back end but change the URI path which is used when accessing
Apache to something else being used to acces Tomcat. E.g. the URI
/jsp-examples/something gets used when accessing Apache and mod_jk
should send this request as /examples/jsp/something to the Tomcat back
If you really need to change URIs, then often mod_proxy is much easier
to set up, because it has specific directives for this (ProxyPass etc.).
With mod_jk you would first need to use mod_rewrite RewriteRules to
change the URI, and then JkMount to forward them. More details can be
The rest of this docs page might be useful as well.
So for example, if I use the alias in the URL -
http://www.mydomain.com/jsp-examples that I send to the Apache server,
and it in turn forwards that request to Tomcat as
http://www.mydomain.com/examples/jsp, I would prefer that the response,
sent back to the user, contains the original, aliased or unaliased,
version of the URL that he/she typed, and not just the resolved version.
As it stands I am always getting the response URL of
http://www.mydomain.com/examples/jsp displayed in the client browser.
What follows is my current version of the config file that I am using
for the jsp-examples. Seems to be working mostly OK, so hopefully I am
on the right track.
FYI - I intend to include these config files in various virtual hosts
configurations each of which have their own document root, hence the
reason for the Alias commands at the beginning of this config file.
Thanks again in advance for any and all offers of help, thoughts, and
