Irules to redirect client ports to port 80

does anyone know how to write an Irule to redirect client port to port 80 . Our applications are redirecting the client browser to the port number utilized on the IIS 6.0 website. It also shows the underlying port number in the client browser.

 

Example of a clent browser response :http://172.16.224.74:9074/LotCheck/auditlist.asp
