mod_jk trying to map every request

[drew]

I'm running Red Hat Linux 7.1, Apache 1.3, Tomcat 4.1.12, and i'm connecting 
with mod_jk.  I have several virtual hosts in apache, some that use tomcat, and 
others that do not.  the problem is that when I check the mod_jk log file, it 
shows that the module is trying to map every single request that comes in from 
apache, even from the vhosts that have no Jk directives.  obviously most of 
them fail, but the only places I have the JkMount directive are in the 
VirtualHosts that actually need them (in httpd.conf).  Everything is working 
properly, i.e. servlets and JSPs load and run appropriately, but i'm afraid 
that given enough time, once traffic starts picking up, too many requests will 
be unnecessarily sent to mod_jk.  Is this just the way mod_jk behaves?  if so, 
won't it hinder performance if there is too much traffic?  it not, does anyone 
know what might be wrong and what i might be able to do to solve it?

I greatly appreciate any help that is given.

Thanks,
-Drew
