Keeping DOM changes intact

[Angel]

I have two HTML pages : page1.html and page2.html

When I click on the "Next" button on page1.html, page2.html is opened

Now on page1.html, I add a table with some content through DOM

Then I press the "Next" button to go to page2.html

Now if on page2.html, If i hit the browsers back button, the table that
i created through DOM on page1.html is lost.

Is there any way to keep the DOM changes intact?

Regards,
Angel
