Nimbostratusreverse proxy server for uri translation
I am new to F5 as reverse proxy server. I have a dns entry pointing to my f5 app.fdn.com. I need to have users that enter app.fqdn.com/app1 be directed to myserver1.com/app1 and users that enter app.fqdn.com/app2 be directed to myserver2.com/app2. It seems that iRules should be able to accomplish this. Any direction or support on how to implement this would be greatly appreciated.
e.g.
