Based on Google Maps, one can track his walking distance using the above tool. After route has been saved, an unique access number is created that points to the route saved. So, when someone returns to the URL, the saved route is displayed: EG:
I would like to know how something like above is possible - does it save the route information (data) in database or xml, create an identifier that points to this database entry or xml file? Any other ideas? Are there any libraries / tools that does this? What kind of languages & software are used?
Our team is trying to create something similar so our users could just access specific data using unqiue urls?
