Edit: I am working on an application that stores the user's learning history and groups users in the school in which they participate. Having two submissions from the same school is unacceptable. In the example below, I set out a specific case (one of many) that confused me.
Obviously, Facebook has a mechanism for detecting duplicate pages, and I'm looking for any solution that takes advantage of this existing functionality.
The graphics API represents these two pages with different identifiers, but at the front end they are redirected to the same page. Take a look:
Note that someone has ~ 21,000 and another has 250. If we enter these page IDs into the browser, see what happens:
Accordingly, those redirected to:
What, as you can see, is the same page! So here is my question:
Is there a way to use Facebook deduplication in my application?
