Subject Re: cacheurl plugin in 3.2.4
Date Sat, 30 Mar 2013 04:33:55 GMT
i have a this in my cacheurl.log

http://r8---sn-5hn7su7s.c.youtube.com/videoplayback?newshard=yes&cp=U0hVSVVPU19OTkNONV9NSVdIOmZ0b250YXNVanNJ&upn=LSlJ_XJrWLg&ip=103.31.34.2&ms=tsu&fexp=912513%2C926502%2C900817%2C916624%2C929809%2C932000%2C906383%2C902000%2C919512%2C929903%2C931202%2C900821%2C900823%2C931203%2C931401%2C912515%2C908529%2C919373%2C930803%2C906836%2C920201%2C929602%2C930101%2C930603%2C926403%2C900824%2C910223&source=youtube&itag=22&ipbits=8&sparams=cp%2Cid%2Cip%2Cipbits%2Citag%2Cratebypass%2Csource%2Cupn%2Cexpire&id=06e26a35933d3cb1&key=yt1&expire=1364545794&mv=m&mt=1364522167&sver=3&ratebypass=yes&signature=071750A18FB381239A3DCFA6CBF25E5A6E444D42.1DB8F36D8F1ACCADB268A2F53ADC6A5DAB33B35C&redirect_counter=1&cms_redirect=yesto
http://video-srv.youtube.com.ATSINTERNAL/itag=22&id=06e26a35933d3cb1

and from what i understand is that the plugins successfully translate
y0utube url to
http://video-srv.youtube.com.ATSINTERNAL/itag=22&id=06e26a35933d3cb1 . But
how do i call the link cause it gives me

*Unknown Host
------------------------------
Description: Unable to locate the server named
"video-srv.youtube.com.atsinternal
(2)" --- the server does not have a DNS entry. Perhaps there is a
misspelling in the server name, or the server no longer exists.
Double-check the name and try again.*


Any suggestion ?
