Query strings are the part of the URL after the question mark (?) that is used to pass information to the web server program. Here is an example of a query string in a URL:


The first_name=John&last_name=Doe&action=Submit part is the actual query string. It is made up of field-value pairs. An equal sign (=) comes after each field name and then followed by the value. Each field-value pair is seperated by an ampersand (&). The question mark is not part of the query string. It is used to separate the path to the requested resource from the query string.
