URL Encoding

15 Oct

You must URL encode any data you’ll pass on in a query string, such as a form post, or other url parameters.

I’m always having to look these up, so this article is as much for my reference as yours.

A URL encoded character is the ascii value of the character preceded with %, with a special case for <space> which is quite common.


Here are some of the most common characters.
