How do you force a web browser to fully reload a web page?

When a web browser is instructed to load a web page, it compares the existing web page with the cached web page.  If changes have been made to the existing web page that are not present in the cached web page then it loads the existing web page.  However if an Adobe Flash file or a picture on the existing web page have the same name as the cached web page then this information will often be loaded from the cache.  This can be an especially frustrating experience.  Some recommend the use of META tags which by themselves have distinct limitations that do not address the issue described.  Some recommend changing the filenames on a dynamic or continuous basis.  This solution works but could be quite elaborate.  I believe the following solution is simple and the most comprehensive.  The following javascript fully reloads the web page once on load:

  1. Javascript (reload.js):

    function reload() {
    if (self.name != '_refreshed_')
    {
        self.name = '_refreshed_';
        self.location.reload(true);
    }
    else self.name = '';

    }

  2.  In the <head> section:

    <head>
    <meta http-equiv="expires" content="-1" />
    <meta http-equiv="pragma" content="no-cache" />
    <meta http-equiv="cache-control" content="no-cache,no-store,must-revalidate,max-age=0" />
    <script src="javascript/reload.js" type="text/javascript"></script>
    </head>

  3. In the <body> section:

    <body onload="reload();">

The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.

You may encounter the following error message when using the L2TP/IPSec VPN Client that is native to the Windows Operating System: "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer."  This error message typically occurs when you are using the wrong Pre-Shared Key for your L2TP VPN.  This error message can occur when other components of your configuration are incorrect but the first thing to confirm is that you are using the correct Pre-Shared Key. If you are using the wrong Pre-Shared Key, the L2TP VPN connection will say Connecting for a long period of time and then display the error message: "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer." If you are using the wrong username or password, the L2TP VPN will immediately respond with: "The remote connection was denied b...
