No problems. I am confused and new too, and of course learning! :) Good 
find too. I didn't think PAC was a generic thing. I thought it was only 
for Tomcat.

Excellent finds. I will share those.

Thanks. Maybe she wanted me to run Apache and not Tomcat. I will have to
talk her about that.

Well, it sounded like Apache httpd and Tomcat are two differnet things. 
Apache for web service/server and Tomcat to add to Apache.

OK. I actually used CCproxy ( and 
got it to work. She wanted me to use Tomcat for another scenario. 

Thanks again. :)
