    This function is called when a user agent for HTTP requests is needed.

    This implementation returns the following value:

    "Mozilla/5.0 (%Platform%%Security%%Subplatform%) AppleWebKit/%WebKitVersion% (KHTML, like Gecko) %AppVersion Safari/%WebKitVersion%"

    In this string the following values are replaced the first time the function is called:
    \li %Platform% expands to the windowing system followed by "; " if it is not Windows (e.g. "X11; ").
    \li %Security% expands to "N; " if SSL is disabled.
    \li %Subplatform% expands to the operating system version (e.g. "Windows NT 6.1" or "Intel Mac OS X 10.5").
    \li %WebKitVersion% is the version of WebKit the application was compiled against.

    The following value is replaced each time the funciton is called
    \li %AppVersion% expands to QCoreApplication::applicationName()/QCoreApplication::applicationVersion() if they're set; otherwise defaulting to Qt and the current Qt version.
