eeergh I think for that regex used for server that began with number or alphabet, an example like this :
http://111.111.111.111:
or
http://mydomain
n the keyword for the regex that u mention above is :
files
as for uploadbaz, I check with different link, allmost all use this :
http://(server_name):(port_server)/uploadbaz.com/(folder_file)/(code)/(filename)
so the keyword is uploadbaz.com, I havent know with other, I only check 5 link

anyway I maybe wrong, but u can creative with regular expression, have fun
