sv_download halp?!

[leet2k]

alright well, for the past half hour i've been in my server config file attempting to get a FastDL working for my server. i've tried so many variations, different webhosts, restart the server via rcon too many times to count. and nothing seems to work. i've read about sv_download and setting up FastDL on many sites, including this forum, steampowered, alliedforums, and countless others.

few variations i've tried to setup FastDL.

Code:

sv_downloadurl "http://leet2k.tk/cstrike"
sv_allowdownload 1
sv_allowupload 1

Code:

sv_downloadurl "http://leet2k.tk/cstrike/"
sv_allowdownload 1
sv_allowupload 1

Code:

sv_allowdownload 1
sv_allowupload 1
sv_downloadurl "http://leet2k.tk/cstrike"

Code:

sv_allowdownload 1
sv_allowupload 1
sv_downloadurl "http://leet2k.tk/cstrike/"

Code:

sv_allowdownload 1
sv_allowupload 1
sv_downloadurl "leet2k.tk/cstrike"

Code:

sv_downloadurl "http://leet2k.tk/cstrike"

and a number others. and i can't seem to get it to work. and honestly, IT'S PISSING ME OFF. so if someone could give me some productive input, it'd be highly appreciated.

much love and thanks,
