Principle for the foreground page main.htm and background action.php through the page frame index.htm organized, the width of the action.php page is set to 0, so that does not affect the display. Action.php the information into a cookie, main.htm the interaction by reading the cookie. Control of the background CGI program can also be achieved in main.htm by re-reading the action.php.
Index.htm
Copy CodeThe code is as follows:


<title>Test</title>





&lt;noframes&gt;&amp;lt;br&amp;gt;&amp;lt;body bgcolor= "#FFFFFF" &amp;gt; &amp;lt;BR&amp;gt;&amp;lt;p&amp;gt; page frames are used, but not supported by your browser. &amp;lt;/p&amp;gt; &amp;lt;BR&amp;gt;&amp;lt;/body&amp;gt; &amp;lt;BR&amp;gt;&lt;/noframes&gt;
