Apache/AJP remote changes the URI. Why? - apache

Question

I'm using Apache 2.4 on Windows and Tomcat 7. Up until now I've been testing everything on my localhost. So my local Apache httpd.conf has this...
<Location /sample>
ProxyPass ajp://localhost:8079/sample
ProxyPassReverse ajp://localhost:8079/sample
</Location>
Now I'm attempting to set Apache up on a different system and point it to my Tomcat system. Here's what the remote Apache httpd.conf has...
<Location /sample>
ProxyPass ajp://192.168.2.93:8079/sample
ProxyPassReverse ajp://192.168.2.93:8079/sample
</Location>
The new Remote Apache is definitely forwarding the request to Tomcat but it's prepending the location to the request. For example...
/sample/sample
When it should be only...
/sample
The only thing that's changed between the local and remote Apache httpd.conf's is I changed the ProxyPass settings from localhost to an IP.
What am I missing here? This is driving me crazy.
Thanks!
Here's my local httpd.conf....

I don't know why the same exact Apache server (literal copy from one system to another) would produce different URI's because I changed localhost to an IP address. But I got it working by removing the <location/> wrapper from the ProxyPass parameters and using these parameters instead...
ProxyPass /sample ajp://192.168.2.93:8079/sample
ProxyPassReverse /sample ajp://192.168.2.93:8079/sample
Hope this helps someone.
