Against each page reload or page switch using back and forward button, "init() and destroy() " methods should not get called when an applet uses <PARAM NAME=legacy_lifecycle VALUE=true>.
This feature works fine on IE and FF browsers but not on google Chrome.

Try to load the following applet and do a page reload

Compare the applet output by running on IE .FF3 and Chrome browser
