Dear Gurus,
For security reasons we have a webdispatcher where we scan the incoming URI's and only allow a specific set of URI calls from HR Renewal to the SAP backend system. There are some URI's that have a number range. For example: /sap/bc/gui/its/webgui/3.109/data. We would like to know what the meaning is of number 3.109 in this example so that we can filter the numbers that are relevant for our setup.
We can work with a wildcard after /webgui so every number is allowed but this doesn't feel right. If we know what the meaning is of those numbers we can filter on a specific number ranger at our webdispatcher wich is more secure.
Hope you can help! 
Kind regards,
