this looks weird me, may i'm missing obvious. following sample tinyurl: http://tinyurl.com/67lwfe it works browser, redirects desired page. when try using curl following: curl -i http://tinyurl.com/67lwfe it responds 200 instead of 3xx response. thought page might responding meta refresh html tag, tried: curl http://tinyurl.com/67lwfe but responds blank no html or meta refresh tags. question how browser knows redirect properly? i've tried setting browser agents no luck. missing obvious? tinyurl appears serve 200 <meta http-equiv="refresh"> initially, 301s subsequent requests amount of time afterwards, can set cookies (two of them!), run ton of tracking scripts, , slow people down. that say, tinyurl sucks, , url shorteners. question.
