Duplicate entries in XML DOM Object

[admin]

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 intomy XMLDOM object.Everything works great but the time when I hit 'Refresh', i.e., F5. Thevalue is still <>"" and gets appended and appended as many times as I hitF5. 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.Maya
