Base62 Encoding: Just one typical tactic is to use Base62 encoding (which works by using sixty two people: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds on the entry inside the databases. This technique ensures that the brief URL is as small as is possible.
Random String Technology: Another solution is usually to produce a random string of a set duration (e.g., six characters) and Verify if it’s by now in use from the databases. If not, it’s assigned into the very long URL.
