Saving Web Pages after accessing the login page.

Question

Hi,
Can anyone tell me how can i save pages after going into the login page through vb.net.
For suppose i log on to amazon.com through vb.net, while using Internetexplorer.application or webclient or webbrowser control.
IE.application i cant find any option to save pages, where webclient and webbrowser do save pages but only the logon page, how can i save the source or the page after i get into the page.

An immediate reply would be highly appreciated.

Best Regards.
