<p>A variable segment is specified in the form <code>{identifier}</code>,

where the identifier can be used later in a request handler to

access the matched value for that segment. This is done by

looking up the identifier in the <code>Params</code> object returned by
|

<code>HttpRequest.match_info()</code> method.</p>
|

<p>By default, each segment matches the regular expression <code>[^{}/]+</code>.</p>

<p>You can also specify a custom regex in the form <code>{identifier:regex}</code>:</p>
|

<p>For instance, to route <code>GET</code>-requests on any route matching
|
|||
|
|
<code>/users/{userid}/{friend}</code> and store <code>userid</code> and <code>friend</code> in
|

the exposed <code>Params</code> object:</p>
