|

<p>Scope is a set of resources with common root path.
|
||
Scopes collect multiple paths under a common path prefix.
|
||
Scope path can contain variable path segments as resources.
|
||
Scope prefix is always complete path segment, i.e <code>/app</code> would
|
||
be converted to a <code>/app/</code> and it would not match <code>/app</code> path.</p>
|
||
<p>You can get variable path segments from <code>HttpRequest::match_info()</code>.
|
||
<code>Path</code> extractor also is able to extract scope level variable segments.</p>
