mod_jk tries to map every request from apache

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
