Maybe I'm wrong, but I see that you are using global xmlHttpReq objects in asynchronous requests. This could lead into problems, because a second (and successive) asynchronous request (i.e. a second vote in the page) will overwrite previous ones if they are not finished and you'll never receive a response from them.

There are some ways of solving this, for example, putting multiple xmlHttpReq objects in an array.

Sorry if I misread your code

    Thanks for that catch, I updated the code to use local variables, some testing shows that this works now. Guess I never though of anyone voting that fast!
