title: Can you put a url in a url? OpenID Connect Redirect URI
body: <p>I'm trying to setup a <code>redirect_uri</code> for <code>OpenId Connect</code>, but my provider <code>Okta</code> tells me it needs to be absolute. So I enter this url:</p>
  
  <p><code>http://example.com/callback</code> and okta accepts it.</p>
  
  <p>Basically I want to open a sign-in window and redirect back to my server by adding a redirect url into the link.</p>
  
  <p>full-link: <code>http://dev1234-okta.com/login/details?details$redirect_uri=http://example.com/callback$moredetails</code></p>
  
  <p>My question is, how can I set the redirect uri to be a url? When I put a url in the redirect uri, my popup just goes to the url and not the dev-1234-okta.com i'm specifying. Can urls have urls inside them? i.e. http link inside a url?</p>
