I'm passing a parameter in the url when I open up a particular page. When
the page loads and finds this parameter, I know that I need to clear a
variable out of the session cache and reset it with a new value. On the
following postbacks I want this variable to remain constant which means I
need to clear the parameter out of the URL before any of the postbacks
occur. Otherwise if this parameter is still in the URL when the page loads
from a postback, it will clear out the variable again.

is there a way to alter the pages current URL?
