Every hop before you click

Paste a short link. The site's server follows it, one redirect at a time, and stops before the destination.

Inspect a link

Hops

Choose a link above to see its hops.

What it will and will not follow

It follows only cse134.site/go/ addresses and links on bit.ly, t.co, tinyurl.com, goo.gl, lnkd.in, ow.ly, buff.ly and is.gd, sends HEAD requests, never reads a page's content, and stops after five hops. When a hop points anywhere else, the address is reported as the destination and not requested. A server that fetched any URL anyone typed would be a tool for attacking other servers, with this site's name on the requests.

Any other link, from a terminal

-I asks for headers only; -L follows each Location, printing every response on the way. Leave off -L to see only the first hop.

curl -IL https://cse134.site/go/chain
curl -I  https://bit.ly/some-link

Neither command loads or runs the destination page: it only asks the server where the link goes.
