    Additional Notes
    1. As font rendering can be slightly different on different platforms/browsers width of the string can vary, it's a good practise to have overal applet width slighly more, than you can consider it's required.
    2. Due to Java security reasons Applet can only retrieve the Last-Modified date for files located on the SAME server where from applet itself was loaded.
    3. Applet would show date correctly only for pages which returns Last-Modified HTTP header. By default server-parsed HTMLs
    don't have this hreader. You can check your server easy with Netscape 4.x in few steps:
      a) open page for which you want to display last-modified date in browser.
      b) Mouse Right Click on the page and select View Info
      c) Look at the Last-Modified: string, if this gives some date than your server is OK to use with this applet. if it's unknown than applet have no chance to obtain this date too.
    In case of server wouldn't return Last-Modified header applet will use today date.
    4. In case of local testing (loaded from file at local HDD) applet wouldn't receive HTTP headers and due to this will show the current date, also in this case applet would be linked back to the hosting page instead of one specified in URL parameter.
