With packet sniffer s/w, I just have noticed that Before accessing wmv or mp4 files there is always URL of "blablahblah../auth/getsid?key=...blah.blah.." parameter.
what is getsid and delsid parameter? Is it request an authentication key from the server and That prevent me from getting mp4 download? And is there any ways to find sid value and make use of that sid value or bypass sid check process for downloading?
I'm sorry for my wierd English and any help would be appreciated.
