Endless URL Shortening Redirection Loop
I wonder if its possible to use 10+ url shorteners in an endless loop of redirection. Can this be abused to cause increased latency to one of the shorteners across their network? I wonder.
- mendicant 15y agoMany will notice if a shortened url goes to another shortener and give a 'security notice'.
- lysol 15y agoI don't think any modern browsers will redirect indefinitely.
- nbpoole 15y agohttp://kb.mozillazine.org/Network.http.redirection-limit http://kb.mozillazine.org/Network.http.redirection-limit All other browsers, to the best of my knowledge, have similar systems built in. So your premise is flawed: you can't have an "infinite redirect."
- jleader 15y ago"This preference affects only HTTP redirects, not redirects with HTML meta tags or JavaScript." So if the shorteners use (or can be configured to use) different redirect methods, it might be possible to get around this limit. However, you'd have to create a chain composed of shorteners each of which either doesn't recognize the next one on the list, or doesn't do any "security" checking at all.
