Redirection Logic: Here is the backend logic that normally takes the quick URL and redirects the person for the corresponding extended URL. This logic is normally implemented in the net server or an software layer.

Hashing: The lengthy URL may be hashed into a fixed-measurement string, which serves given that the short URL. On the other hand, hash collisions (distinctive URLs resulting in the identical hash) have to be managed.
Base62 Encoding: One particular prevalent approach is to make use of Base62 encoding (which utilizes sixty two people: 0-nine, A-Z, in addition to a-z) on an integer ID. The ID corresponds to the entry inside the database. This process makes sure that the limited URL is as limited as you possibly can.
Random String Generation: A different tactic is usually to crank out a random string of a set size (e.g., 6 characters) and Test if it’s previously in use within the databases. If not, it’s assigned to the very long URL.
