JQuery File Upload on IIS running PHP - 405 Error

JQuery File Upload on IIS running PHP - 405 Error

I just install "JQuery File Upload" plug-in on an IIS 7 server running PHP.  I am getting a 405 error, which is a POST error when I "Start" the upload.  When a look at the log it is showing a POST to /server/php/ without calling any program.

I think the plugin is designed so that it assumes that the web server will run the default file that is located in  /server/php/.  I'm guessing that this would be the UploadHandler.php - but it is a guess, I'm not sure.  I've tried debugging in Chrome so that I can add the file name to the URL - but have not found it in the code.

I've looked at the code but cannot figure out where this is being passed and whether or not I can specify a file so that I don't get the 405 error when I click the "Start" upload button.

Is anyone running IIS with PHP who has implemented the JQuery File Upload?  Any help would be greatly appreciated.
