How to rewrite the request to sub-folder to another application in IIS

Question

if user request to http://my.example.com/pages/uc?dc=qXE7kHEIHHiT2Gexv%2bLDy63yqTeh3gcHsd%2bBrn6vn4%2bArW0gmwv8nw9

then it should be rewrite to http://qa.example.com/uc?dc=qXE7kHEIHHiT2Gexv%2bLDy63yqTeh3gcHsd%2bBrn6vn4%2bArW0gmwv8nw9

The user should not be able to see the URL changes (user should never know its a different application)
