Back Button using viewstate

Hi

I have two pages in my web app. The first page has a grid view of a list of items, beside each row entry, I have a 'View' button. On clicking the 'View' button it navigates to the second page which contains a tabbed view of detailed information/view of the corresponding row entry we clicked on the first page.

Now, what I need is a BACK button on the second webpage which on clicking will take me to the first page. Presently I have a simple back button created in the second web page, but it takes me through each view, whatever I had done in my present page, before it navigates me back to the first page. Im trying to create a back button which will skip any operations or tabbed views i have gone through in the present page (Second page) and will take me to the last instance of the first page.

Any ideas or suggestions?
