You need to create a new session so that ND will process the request. i.e.:
//[[SPIDER_EVENT<OK_onWebEvent>
public int OK_onWebEvent(CSpWebEvent event)
{
int command = PROCEED;
try
{
if(CSpider.removeUserSession())
{
command =
CSpider.makeNewUserSession(this.getMainProject());
if(command == PROCEED)
{
// Take them all the way out
CSpHttp.setAutoMode(false);
CSpHttp.reset();
CSpHttp.setHttpStatus(302);
CSpHttp.write(CSpider.getOutputStream(), "Location: http://wherever" +
"\n\n");
}
else
{
// You will ned to stream some html
here...
}
}
else
{
// You were unable to remove the user's
session so you may load any ND page...
}
}
catch (Exception ex)
{
// whatever you want to do here
}
return(command);
}
//]]SPIDER_EVENT<OK_onWebEvent>

Subject: [ND] Can't execute RemoveUserSession in ND4 on logout
Hi,
We moved from ND3 to ND4 recently and have come across a number of
problems. One such problems relates to CSpider.removeUserSession().
On a logout page we call an external URL (from a button webevent that
runs a script to disconnect the user from the database (this is inside
our firewall). Upon returning to our project a call is made to
CSpider.removeUserSession() with drastic results.
** The HTML error we see is -
A severe application error occurred. Please notify the System
Administrator immediately!
Note to the developer: An un-caught Exception has probably occurred in
one of the events that have been implemented on the Project class.
** The Log error we see is -
spider.control.CSpWebEventProcessor:c:930674037927:w:930674042786:crea
teDefaultSessionEnvironment: Creating a default Session environment as
a way to recover
I've seen the other suggestions in the forums (move call to the
OnBeforeHTMLOutput event etc.) We have tried this we no success. If
anybody can help or suggest an alternative method for cleaning up a
user session it would be appreciated.
