i am storing loaded user controls in the Cache object. i can turn the
feature on and off with a Web.Config setting. when i am using objects from
Cache is seems to be affecting my response HTTP headers. the error message
upon doing a Context.Response.Redirect is:

"Cannot redirect after HTTP headers have been sent."

i do not get this error when NOT loading from the Cache object! Buffer is
set to true. ANY IDEAS?????????

Before doing the redirect, use the following code:
    Context.Response.Clear()
'Redirect' works by setting the HTTP response code to 302 (Object moved) and
sending 'Location: <new url>' as the response content. This doesn't work
when there are already headers sent (which is a gotcha when trying to set a
cookie and redirecting at the same time).

i am still getting the same error with Clear() before the Redirect. i
wonder if the error message is misleading. can't imagine why using the
Cache object would affect the headers.
