You can enable your system to automatically replace user-posted outbound links with safe links pointing to YOUR OWN subdomain (not to Sur.ly), for example: all links like
http://sur.ly/o/domain/AA000014 will change to links like
http://safe.example.com/domain/ where 'safe' is your subdomain and 'example.com' is your TLD.
For this you need to:
1) Choose a new subdomain's name (example: safe.example.com where 'safe' is a custom name you need to choose).
2) Sign in to your DNS management account and create new CNAME record and set
safe CNAME external.surdotly.com
DNS changes may take 24 hours to propagate.
3) To add your subdomain, please, sign in and go to Admin Panel (Account -> select your site -> Use your subdomain)
4) Set up Sur.ly SDK according to one of the instructions below.
