Redirect check: "bit.ly"

HTTP redirect (a.k.a. web forwarding) is used when you want to send browsers/visitors from one URL to another automatically. This can be because you've switched domain names, and you don't want to lose people who still arrive on the old URL, or because you use an easy-to-remember domain (e.g. firefox.com) but the actual content is on another website.

HTTP redirection

     Original URL: http://bit.ly/33cIwVB
     DNS: bit.ly → 67.199.248.10 • 67.199.248.11
     Immediate privacy upgrade ↪ https://www.youtube.com/watch?v=dQw4w9WgXcQ
     Permanent redirection (301) - Search engines will eventually only index the destination
     Redirect ignores querystring: http://bit.ly/33cIwVB?<var=abc> ↪ https://www.youtube.com/wat…

HTTPS redirection

     Original URL: https://bit.ly/33cIwVB - check HTTPS config settings for bit.ly
     Immediate redirection ↪ https://www.youtube.com/watch?v=dQw4w9WgXcQ
     Permanent redirection (301) - Search engines will eventually only index the destination
     Redirect ignores querystring: https://bit.ly/33cIwVB?<var=abc> ↪ https://www.youtube.com/wat…

CONFIG CODE: P-sU1-SR1

This config code is a simple representation of the redirection policies on this server. It's an easy way to compare two sites without reading all the text.
