URI query

The query is indicated by the first question mark (?) character and is terminated by a number sign (#) or the end of the URI:

https://example.com/collection?<query>

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.
