subdirectory of a website request to another server using LB

[Faisal Kolliyath]

I have a portal with domain name; example.com , and it is bound to a Web Application that is running on a machine with IP address 111.111.111.111 .I also have another web application running on a machine with IP address 222.222.222.222. So,what i need is when server receives an HTTP request with a URL that contains a subdirectory named MobApp it shall redirect to the IP address 222.222.222.222.

For example;

If request url is something like example.com/OldApp or example.com then request shall be served by the web application running on machine with IP address 111.111.111.111

if request url starts with example.com/MobApp then request shall be served by the web application running on machine with IP address 222.222.222.222
