     Does |response| to |request| match |source list|?
   </h5>
 
-  Given a <a for="/">request</a> |request|, and a <a>source list</a> |source list|,
-  and a <a for="/">policy</a> |policy|, this algorithm returns the result of executing
-  [[#match-url-to-source-list]] on |response|'s <a for="response">url</a>,
-  |source list|, |policy|'s [=policy/self-origin=], and |request|'s
-  <a for="request">redirect count</a>.
