Editing Query string (section)

== Example ==
If a [[Form (web)|form]] is embedded in an [[HTML]] page as follows:
<syntaxhighlight lang="html">
<form action="/cgi-bin/test.cgi" method="get">
  <input type="text" name="first" />
  <input type="text" name="second" />
  <input type="submit" />
</form>
</syntaxhighlight>

and the user inserts the strings "this is a field" and "was it clear (already)?" in the two [[Text box|text fields]] and presses the submit button, the program <code>test.cgi</code> (the program specified by the <code>action</code> [[HTML attribute|attribute]] of the <code>form</code> [[HTML element|element]] in the above example) will receive the following query string:
<code>first=this+is+a+field&amp;second=was+it+clear+%28already%29%3F</code>.

If the form is processed on the [[web server|server]] by a [[Common Gateway Interface|CGI]] [[Scripting language|script]], the script may typically receive the query string as an [[environment variable]] named <code>QUERY_STRING</code>.
