When adding the Session ID parameter you have to decide whether you want the user to choose their own Session ID or if you want to make the session ID un editable.
Firstly, the choose their own method. The HTML line you need to add is:
<param name="SID" value="Enter name">
The value= entry is what the user will see when prompted. Another example would be "Please enter a unique ID?".
So with this line added the applet code may look like the code on the right (top).
Secondly the un editable option. This simply requires you to choose a session ID and place a "*" before it. An example is shown below:
<param name="SID" value="*speedtestnewyork">
With the HTML line shown above any test performed will be tagged with the session ID speedtestnewyork.
This will not be editable by the user. Again, the applet code will look something like the code on the right (bottom).
Automatically Pass a Unique Identifier for the SID
