How to save game in a dropbox hosted unity web app?

Hello, I’ve made a complete game in Unity3D 4.0 and put it in a dropbox public folder to acess it as a facebook inframe app, everything working great until the game tries to save the best score. A serialization is used to save the best scores, and it works fine when I play a standalone version, but not when I play the web version (even hosting in my computer), have someway to save the best score in the web version? And I’ll have some problem in writting the save data to dropbox?

When running in a webplayer you have no access to the hard drive of the computer. To save the high score you’ll either need to use player prefs, or else write the data to a remote server.
