The query of a URI is the section that comes after the path. It contains non-hierarchical data to identify a resource within the scope of the URI's scheme and naming authority along with data in the path component.

Syntax

?query

query

A sequence of any characters, except for the # character, which starts the fragment. The exact format of the query is defined by the resource itself.

Description

Consider the following URL:

http://www.example.com:80/path/to/myfile.html?key1=value1&key2=value2#SomewhereInTheDocument

?key1=value1&key2=value2 is the query component containing parameters for the web server to process. The specific parameters in the example are a list of key/value pairs separated by the & symbol. Web servers can use the parameters to modify responses, like applying filtering, search, or sorting results, although this is implementation-specific.
