The dispatcher compares the PathInfo property of an action item to the PathInfo of the request message. The value of this property should be the path information portion of the URL for all requests that the action item is prepared to handle. For example, given this URL,

http://www.TSite.com/art/gallery.dll/mammals?animal=dog&color=black

and assuming that the /gallery.dll part indicates the Web server application, the path information portion is

/mammals

Use path information to indicate where your Web application should look for information when servicing requests, or to divide you Web application into logical subservices.
