From Url:  the friendly URL you wish to create.   It should be a relative URL since it will be only work when someone is on your HandsOn Connect site.    (A relative URL is one where you don't have to put in the https://volunteer.troutco.com if that's your site URL.  

To URL: This is the URL you wish to redirect to.  If the URL is on your public site or sharing portal, just use a relative URL.  If the URL is to an external site outside your CMS., then put the full URL including https://     (For example if you were putting in the URL of a file coming from your Salesforce instance, or another website outside your CMS).

Type:  Choose either Permanent (301 Redirect) or Temporary (302 Redirect).  
These determine how search engines handle this.  Use Permanent if this will always be in place.  Use Temporary if you only plan to redirect for a while and eventually want the original URL to be accessed and no longer redirected.

Active:  Check this box to make the URL live and active.  Uncheck to stop redirection.

Click SAVE when finished.
