hide the bachend systems

Gurus:

We have an EP with ESS application. Employees use a webdispatcher URL to access the EP doing ESS related

jobs.

We face an issue that is HttpWatch can display the hostname of each visited backend system while the EP end user navigates on the EP.

Could you please share your experience on how to overcome this issue, in other words, let no tools like httpwatch be able to display the visited backend systems?

Thanks!!
