Urgent: How to redirect ITS ?

When testing /default_host/sap/bc/gui/sap/its/ on ECC6's SICF, the URL

will be:

http://<ITS server's FQDN>:8000/sap/bc/gui/sap/its/webgui?sap-client=200

We have a need to re-direct the ITS, so that the URL will be

http://<any server's FQDN>:8000/sap/bc/gui/sap/its/webgui?sap-client=200

Please advise how. Points guaranteed. Thanks!
