Dear all,

I need to do backward in a web browser. Both the current and previous web page
are created by servlets. If I need to backward to the previous one and try to
keep the values (such as data in a table) in the previous page, how can I do
that? It seems that JavaScript doesn't work because it needs to specify the
HTML file name of the previous one. If I use the servlet that created the
page, all the data in the page needs to be filled again. It is bad.

Could you give me some ideas?

Thanks,
Li Bing
