I have a querystring, http://url.com/page.aspx?step=1&c=123
I would like to be able to set the step number. Ie. when somebody is on the page http://url.com/page.aspx?step=1&c=123 and they click a button, it fires an event that grabs the current url, modifies the querystring value "step" so it equals 2, and then does a response.redirect to the new url (http://url.com/page.aspx?step=2&c=123)
What is the easiest method for doing this?
