Redirection Logic: This is actually the backend logic that takes the quick URL and redirects the user towards the corresponding extensive URL. This logic is frequently applied in the online server or an application layer.

Base62 Encoding: A person popular approach is to implement Base62 encoding (which makes use of 62 figures: 0-9, A-Z, plus a-z) on an integer ID. The ID corresponds on the entry from the database. This method ensures that the shorter URL is as brief as you possibly can.
Random String Generation: Another tactic is usually to create a random string of a fixed size (e.g., 6 people) and Examine if it’s currently in use during the databases. If not, it’s assigned for the extended URL.
