RewriteRule inside JkMount location
Hi!Apache 2.2.11, mod_jk 1.2.28
httpd.conf:
LoadModule jk_module modules/mod_jk.so
JkOptions +ForwardURICompat
JkMount /app/* balancer
LoadModule rewrite_module modules/mod_rewrite.so
DocumentRoot /var/www/public_html
.htaccess in docroot:
RewriteEngine On
RewriteCond %{QUERY_STRING} !dyn\=1
RewriteRule ^app/ntd/give.* give.shtml/?%{QUERY_STRING} [L]
I cant get worked this conf on apache 2.2.11, URI http://server/app/ntd* pass
to tomcat omitting RewriteRule. But its ok on apache1.3.33 + mod_jk1.2.14
(even whitout JkOptions +ForwardURICompat, AFAIK its enable by default for
mod_jk <= 1.2.22).

So, i found that its work only if condition begins with /
RewriteRule ^/myapp/some?(.*) /script.shtml?%{QUERY_STRING} [L,PT]
Other conditions, not under /myapp/ works without first / ok.

Hi, Rainer!
Thx for you answer, its look like good solution, but anyway ignoring
line BEFORE JkMount - a bit stupid behavior.
RewriteRule ^myapp/some(.*) script.shtml%{QUERY_STRING} [L]
# Line above will be ignored
JkMount /myapp/* balancer
May be this is just a bug?

... and you can also use mod_rewrite to set the environment variable
"no-jk", which disables mod_jk forwarding.

Hi.
Let me jump in here for a while.
First, I think it would be clearer (and certainly more efficient), to
move your Rewrite rules away from a .htaccess file in docroot, and just
put them in your main Apache configuration files.
(I suppose that if you have access to the DocumentRoot, you have access
to the server (or virtual server) *.conf, yes ?)
Second, I personally find another syntax clearer than JkMount, specially
when you need to combine it with other rules in Apache.
The main reason is that indeed, it is not always very clear which kind
of "priority" JkMount/JkUnMount directives have, vis-a-vis Apache
Rewrite, <Location> etc..
So, for example, instead of writing
JkMount /myapp workername
JkMount /myapp/* workername
you can also do it as follows :
<Location /myapp>
SetHandler jakarta-servlet
....
</Location>
This is explained here:
http://tomcat.apache.org/connectors-doc/reference/apache.html
in the section entitled :
Using SetHandler and Environment Variables
Basically, the <Location> section above means that anything
corresponding to a URI starting with "/myapp" will be passed on to
Tomcat. It is thus equivalent to the duo
JkMount /myapp workername
JkMount /myapp/* workername
but, in my view, it gives you more flexibility at the Apache level, and
also fits better with the Apache "way of things".
I think it makes the respective priorities of mod_jk and RewriteRules
clearer, because they are the same as what they are in Apache between
Rewrite and <Location> blocks.
For example, if you load the mod_setenvif module in Apache, you can
exclude some URI's inside of that location using this kind of thing :
<Location /myapp>
SetHandler jakarta-servlet
SetEnvIf REQUEST_URI "\.(css|gif|jpg|js|html?)$" no-jk
....
</Location>
meaning that URI's for files starting with "/myapp" but ending in one of
the extensions above will /not/ be passed to Tomcat (but the rest will).
You can also add a second <Location> like
<Location /myapp/no-tomcat>
SetHandler none
....
</Location>
so that most things starting with "/myapp" will go to Tomcat, except the
ones starting with "/myapp/no-tomcat".
And of course, you can use <Location>, <LocationMatch>, <Files>,
<FilesMatch> etc.. to similar effect.
Which seems to me the kind of thing you want.

Re: RewriteRule inside JkMount location
Posted by J Channel <jc...@gmail.com>.
I found that its work ok with httpd.conf like this:
...
JkMount /app/* balancer
JkUnMount /app/ntd/* balancer
...
But this is not very well cause i need to add many exception pathes
like this to httpd.conf :(
I just need to have mod_rewrite directives with more priority than JkMount.
Just like in apache1.3+mod_jk1.2.4
How can i tune this?

I send URL http://testsite.net/app/ntd/give?someparams=value
And i give a tomcat page "Sorry, we have no such page" instead of my
http://testsite.net/give.shtml?someparams=value page.

Now all URL under app/* just pass out to tomcat.
I expect redirection to give.shtml by RewriteRule as it works in
apache1.3 with same configuration.

I have no problem with pass through, i have problem with ignoring my
rewrite directives under /app/*

It would be nice, if you would tell us, which URL you send, what you
expect to happen, and what happens instead.
General comments:
- do not use any Forward JkOptions unless you are sure you need them and
understand the implications. So I suggest you drop the respective line
- if you want mod_jk to be called even when mod_rewrite interfered with
the URL, you need to add the PT flag to the rule (OT=pass through), so
switch from "[L]", to "[L,PT]".

Rainer
