How can view the visited web site
after closing
internet connection( "offline)
I am using "IE6" browser..

Before closing connection:
File - Save as - Complete Webpage

If that was not the solution you were looking for, tell us more about what exactly you want to do.

Another way is to display your page then hit "print screen" (PrtSc), this saves a picture of the web page; open your word processor and select edit/paste and, viola, there it is. A proper screen-shot program, usually a sub-function of a graphics program, would do a better job
