A request URI used by a client application looks something like this:
http://myPASServerHost:8110/OnlineStoreWebApp/web/OrderService/Order
It is important to know what parts of this URI you, as a service developer, control. The host and port (myPASServerHost:8110) and also usually the web application name (OnlineStoreWebApp) is determined by the administrator who deploys the web application. The remainder of the URI, which includes the transport (web) and the service endpoint (/OrderService/Order) is determined by how you design your API.
