Upload Webplayer

How would I go about putting up a webplayer for my game to test it and share progress? I see people put them up but I dont know how they do it XD

This might help explain things.

actually ass, I have tried that. I was implying how to get it onto one of the webhosts; it is not that hard to figure I need a host. Which one would be a better contribution since not all webhosts support the file.
