URL encode

What’s URL encode?

URL can be sent only ASCII characters over internet. When doing http request with query parameters, query parameters are needed to be encoded. It is called as percent encoding. It is defined in RFC3986.

How to do URL encode

Basically encode only values in query parameters to avoid collision of keys and =.

E.g.
http://example.com/?key1=value1&key2=value2....
