Query string

In the World Wide Web, a query string (or querystring)is the part of a uniform resource locator (URL) containing data that does not fit conveniently into a hierarchical path structure.

Description

The query string commonly includes fields added to a base URI by a Web browser or other client application, for example as part of an HTML form.

Web servers handle query strings

A web server can handle (process, respond to) a Hypertext Transfer Protocol request using one of two methods: [Static web page|static] or dynamic.

Static web page

• Reading a file from the server's file system based on the URL path
• See Static web page.

Dynamic web page

• Handling the request using logic that is specific to the type of resource
  • The query string is available that logic for use in its processing
  • See Dynamic web page.
