Just wondering about advice concerning the driver and controller being spread out by tomcat balancing via mod_proxy. As I have mine set to port 8080 but whats the best option should traffic flow increase? I thought of balancing at port 8080 across servers because on testing I had problems with other ports 8081 8082, etc... I had my webservice linked with domain name rather that IP (AS I also notice that the webservice IP in the database kept switch between servers). Which begs the question of reliability when doing this aproach. OR does the controller simple queue txt as they arrive so as to not overload? And out of curiosity how much can the controller tackle? Care to share?
