SYMPTOMS
When you download Java applets with Microsoft J++, Internet Explorer sends an incorrect value for the HTTP_USER_AGENT request variable.
This occurs for Microsoft Windows 2000 Professional, Service Pack 2, that runs Internet Explorer 5.5, Service Pack 2: Mozilla/4.0 (compatible; MSIE 5.5, Windows NT 5.0; T312461).
When the browser tries to download a Java applet that is indicated in an
Mozilla/4.0. (compatible; MSIE.5.0; Win32)
CAUSE
This problem occurs with the Internet Explorer HTTP GET Request because the User Agent is incorrect for Java applets. This occurs because the string that is associated with the HTTP.agent is taken from the hkcu\software\microsoft\windows\currentversion\internet settings\User Agent.
RESOLUTION
To work around this problem, you can modify the registry key that the Java applet is using to the USER_AGENT of the respective browser. Note that this is a client-side fix. Therefore, the following change must be made for all client users:
hkcu\software\microsoft\windows\currentversion\internet settings\user agent
Example:
For Internet Explorer 6.0 on Microsoft Windows XP with the .NET Framework installed, change to:
Mozilla/4.0 (compatible; Microsoft Internet Explorer 6.0; Windows NT 5.1; .NET CLR 1.0.3705)
