Answers to Questions (FAQ)
What is URL encoding?
A URL can only be composed of a limited number of characters: 10 digits (0-9), 26 lowercase letters (az), 26 uppercase letters (AZ), and some special characters' - ,. , _ , ~ ,? , # ,% '
To write other characters, use URL encoding, writing them with the character % as %code.
How to decompose an URL?
A URL can be split down into several parts:
Example: here
| Scheme | http or https |
| Host | google.com |
| Port (optional) | 80 or 443 |
| User (optional) | |
| Pass (optional) | |
| Path | /search |
| Query (after the "?") | q=test&hl=en |
| Fragment (after "#") | id |
The contents of the query string (query_string) can also be decomposed
Example: q=test&hl=en has 2 parameters, q which has the value test and hl which has the value en
This work is usually done by a URL parser, present on browsers, and on this dCode page.
How to decrypt % in a URL?
By default in a URL, only alphanumeric characters (letters and numbers) are allowed as well as a short list - _ . ! ~ * '(). All other characters must be encoded with a %. An exception for the space character that can be encoded with a +.
Example:
| %20 | space |
| %3C | < |
| %3E | > |
| #23 | # |
| etc. |
More generally any character can be encoded in HTML4 with its ASCII code (more precisely Windows-1252 encoding) and since HTML5 in UTF-8.
