It is possible to have different URLs (see below) to invoke the same webroutine as a webpage.
Let's look at the definition for an example webroutine, MaintainRecord:
Based on the WEBROUTINE definition, this webroutine can use the optional ServiceName property on the WEBROUTINE definition to invoke the WAM:
http://<server>/cgi-bin/lansaweb?srve=MaintEmployee&part=DEX
The ServiceName does not require further qualification, as it must be unique across the partition.
The second URL option uses the combination of WAM name and the webroutine name as a unique combination.
http://<server>/cgi-bin/lansaweb?wam=WAMEX02&webrtn=MaintainRecord &part=DEX
