IIS7 can support pages without extensions without administrator configuration settings. IIS6 can also support URLs without extensions, but it requires an administrator setting. Here's a tip on how to configure IIS6 to support URLs without extensions.
On the website properties, The configuration tab must be selected.
A wildcard application map must be added. Select the INSERT option and add the following file, and turn off the checkbox to verify the file exists.
The new setting should now be in place.
This should now allow URL rewriting on URL's like: http://e3retail.com/page/products/.
