    // javascript associative arrays are crap, conflict with prototype declarations
    // ie6 doesn't support javascript const
    // div padding increases the div's width
    // <input type="image"> submits the x,y coordinates
    // <select> without any options doesn't get submitted with the form
    // neither does any input without a name
    // Transfer-Encoding: chunked is interesting, don't need a Content-Length header
