I have a logic in my ASP Page where I check the value of the parameter Request("txtText")
supplied to me. If the value <>"" then I append this text as LastChild into
my XMLDOM object.

Everything works great but the time when I hit 'Refresh', i.e., F5. The
value is still <>"" and gets appended and appended as many times as I hit
F5. Ooh...

Does anybody have any good idea how to "Clean" this parameter?
I've experimented with Response.Flush, Response.End but didn't help. Also,
does anyone know if ASP Page supports KeyUp event?

Please help.
Thank you all for your input.
