back button on response.redirect?

Hi..

I am very very new to asp.net.. I have a windows forms application and a web browser container in it and in this container I am calling my asp.net web page from a server. Now this web browser does not have a back button so how do I manage a back button so that when the use clicks it, it goes to the back page..??

Please note that I am also using response.redirect() sometimes in my pages.. so when the user clicks the back button, the control should take him eactly to the previous page.. now how will asp.net remember the last page on a response.redirect?

Please explain with a code sample...

Thanks..
