At any rate, with mod_jk loaded before mod_rewrite (in my case, I am able to simply perform the include of mod_jk.conf-auto before I do any rewrites) it seems to work.

tell us what you are trying to do and send us some
sample config files and
how your environment is setup. is becomes much
easier than to answer the
question above, because alias works very well for me
:)
Well, actually, I've twice posted detailed
descriptions of what I'm trying to accomplish on this
topic and gotten zero replies, but here goes another
attempt...
I'm using Apache 1.3.14 and tomcat 3.2.1 with
mod_jk.c. I don't know if the latter is the 'latest'
version of mod_jk.c - I grabbed it from the tomcat
download site two weeks ago. I am running this on
WinNT using downloaded binary versions of the relevant
software.
I have setup my application ("myapp") as a directory
inside the webapps/ directory, complete with WEB-INF
subdirectory and such.
I have apache configured to apply an alias or a
rewrite rule to a reqest:
#--
IfModule !mod_rewrite.c
LoadModule rewrite_module
n:/opt/local/apache/modules/ApacheModuleRewrite.dll
/IfModule
RewriteEngine On
RewriteLog log/apache_logs/rewrites.log
RewriteLogLevel 9
RewriteOptions inherit
RewriteRule ^/myapp/(.*)/common/(.*) /myapp/common/$2
#-
I can tell from the rewrites.log that it is indeed
getting applied:
(2) init rewrite engine with requested uri
/myapp/folder1/common/mypage.jsp
(3) applying pattern '^/myapp/(.*)/common/(.*)' to
uri '/myapp/folder1/common/mypage.jsp'
(2) rewrite /myapp/folder1/common/mypage.jsp -
/myapp/common/mypage.jsp
(2) local path result: /myapp/common/mypage.jsp
(1) go-ahead with /myapp/common/mypage.jsp [OK]
The idea here is simple: the request
/myapp/folder1/common/mypage.jsp
should result in a request for
/myapp/common/mypage.jsp
The rewrite rule works great. This works great for
static stuff (i.e. html) served up by Apache.
The *problem* is that Tomcat is not getting the
translated request, it is getting the original one:
/myapp/folder1/common/mypage.jsp
Since no file in that path actually exists, naturally
it returns a file not found error. Tomcat DOES
happily find, compile and execute requests for
servlets and jsp pages that are in paths that do exist
such as
/myapp/folder1/myother.jsp
I have apache configured to send requests to tomcat
via ajp13 by including mod_jk.conf-auto just after the
above rewrite rule:
# include configuration for tomcat servlet engine:
#
Include n:/opt/demo/conf/mod_jk.conf-auto
#
I've configured server.xml very minimally, no custom
contexts or anything. About the only thing changed
here is I've enabled ajp13 and then setup
workers.properties to map requests to it. I doubt any
of this is relevant because I see the exact same
behavior even with 'raw' server.xml and
worker.properties files.
Note that I get the same behavior if I use an Alias
instead of a rewrite:
#--
Alias (.*)/myapp/(.*)/common/(.*) $1/myapp/common/$3
#--
This rewrites static requests served by Apache, but
just like with rewrites, gets ignored by tomcat.
That's pretty much it.
Any suggestions as to what is (or is not) going on?
Basically, what I want to happen is that, after a
rewrite rule has been applied, that Tomcat should be
processing the modified URL, not the original.
Thanks in advance for any help!

I.E., it always generates statements like: JkMount /myapp/servlet/* ajp12 JkMount /myapp/*.jsp ajp12 I've even tried disabling all reference to ajp12 from server.xml and workers.properties but that had no effect. Is the only way to force the use of Ajp13 to manually edit the mod_jk.conf file? as told here you can tweak things, but the most clean is to use a separate my-mod_jk.conf include file that you derivate from the generated mod_jk.conf-auto if you really want all to be automatic add a conversion script (sed or perl script) to generate the my-mod_jk.conf from the .conf-auto with cocoon and HTTPS I had to tweak thos .conf-auto much more and nothing is better than manual config when things are stable... changing the ajp12 alias to point to ajp13 is really anti-documentation... on unix try something like #!/bin/sh launch_tomcat sleep 5 # wait for tomcat to generate the .conf-auto sed -e 's/ajp12/ajp13/g' conf/mod_jk.conf-auto conf/my-mod_jk.conf launch_apache don't forget to adapt apache conf/httpd.conf to include the my-mod_jk.conf instead of the conf-auto - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Re: ajp12 vs ajp13 mod_jk.conf-auto
yes, the JkMount command looks like this JkMount context workername so the autogenerated ajp12 is just the worker name "ajp12" in the workers.properties file you can change the protocol that the worker is using. the property file has the following format worker.workername.propertyname=value worker.ajp12.port=8007 worker.ajp12.host=localhost worker.ajp12.type=ajp13 so just change the last line to use ajp13. now you have to modify server.xml to start a ajp13 connector on the port 8007 and change the port for ajp12. the nice thing with the autogenerated file is that your webapps can be dynamic. but if you need to do a lot of fancy stuff, you should create your own file for the mod_jk configuration. try playing around with it, and if you have a specific problem let me know and I can help you out.
