[Magicajax-cvs] magicajax/Core/UI/Controls AjaxPanel.cs,1.3,1.4

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Update of /cvsroot/magicajax/magicajax/Core/UI/Controls
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17135/magicajax/Core/UI/Controls

Modified Files:
	AjaxPanel.cs 
Log Message:
Code-changes to use SHA1-hashcode for comparing last generated Html with current generated Html. This saves lots of server memory.
Also, the 'NoStore' mode doesn't have to use Session anymore to store it's Html data, but instead uses hidden fields on client (so it's now really 'NoStore').
