Preserve viewstate between pages

[Mondeo]

I have a page index.aspx which contains a user control, the user control is a search module and has drop downs for the search criteria, it also has a search button.

When the button is pressed it calls reponse.redirect to a search results page. Is there anyway I can preserve the values of the dropdowns on the user control between different pages?

Thanks

When you redirect you could just add ?Criteria=blabla, and then just read the variable on the other end?
