It might be a browser bug. It looks like the browser is interpreting
src="/qamino/backoffice/swf/check.swf... as src="qamino/backoffice/
swf/check.swf (note lack of leading /. You could try fully
qualifying it: src="http:.//www.domain,com/qamino/backoffice/swf/
check.swf...
Otherwise, I'd try to catch it at the web server (Apache?) and use a
rewrite rule to guide it to the correct place.

Thanks guys for the advice now I know what creates a new session,
it's a flash component in the page but why!!
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
id="menu" codebase="http://fpdownload.macromedia.com/pub/shockwave/

height="17">
<PARAM NAME="allowScriptAccess" VALUE="sameDomain">
<param name="movie" value="/qamino/backoffice/swf/check.swf?
id=1854472855&state=on"></param>
<PARAM NAME="quality" VALUE="high"/>
<param name="bgcolor" value="#F3F3F3"></param>
<embed pluginpage="http://www.macromedia.com/go/getflashplayer";
allowScriptAccess="sameDomain" type="application/x-shockwave-flash"
quality="high" src="/qamino/backoffice/swf/check.swf?
id=1854472855&state=on" align="center" width="17" height="17"
bgColor="#F3F3F3"></embed>
</object>
So when I trace the uri() in the dispatchRequest, the new session
comes from : /qamino/backoffice/swf/check.swf?
id=-1183135035&state=on
How can I avoid this new session?
May I just test something like that and retrun null?
public WOResponse dispatchRequest(WORequest request) {
if (request.uri().indexOf(".swf") >0)
return null;
else
return super.dispatchRequest(request);
}
Thanks

In addition to Mark's excellent advice, check any JavaScript you
are using. If a link is submitting the form, ensure that the
script is returning false. Another good debugging technique for
this is to override dispatchRequest in Application and log out
request().uri(). This, combined with the session logging below,
will show were in the page the errant request is coming from.

Hi Sébastien,
If this problem happens every time then I would use the debugger
and set a break point on session creation to see what's happening.
When that's not the case, when it happens intermittently then I
sometimes resort to something like this. I override the session
constructor and log when the session is created, it's sessionId
and the stackTrace so I can see exactly how the session is being
created. This has been very enlightening over the years. I hope
it helps:
public Session() {
super();
String message = "Session created (sessionID:" + sessionID
() + ")";
NSLog.err.appendln(message);
new Exception(message).printStackTrace();
}
When a session is created in response to a component action, the
output will look something like this:
[2005-06-20 08:25:00 EDT] <WorkerThread0> Session created
