Preventing second static HTML page from loading
<p>I have a link on a page. When the user clicks the link a static HTML page loads.  I would like to prevent the user from launching a second instance of the same static HTML document. </p>

<p>I'm thinking some javascript up front in the static HTML page might do. Basically if the script detects that there is already an instance of the static HTML document loaded  then a Javascript pop-up would indicate to the user that 'document is already loaded" (something like that). </p>

<p>Anyhow, Java script is not my strong point so wondering if someone can please shed some light on this. </p>
