filter increase number of session
Hi at all,
I have problem using filter in my web application under tomcat (tomcat 4.1
on Windows 2k OS).
Client of the web application is an IVR (Interactive Voice Response) in the
context of voice-xml application.
I have configured a filter in order to log all the request (included all the
parameters) to my web application and I realize that tomcat makes a new
session for every request to a URI of my web application.
So, especially if I set a high value for session timeout, when I have a
discrete number of call in the same time, the number of active session
increases vastly.
If I disable the filter that problem doesn't occur anymore and I have a
single session for every phone call.
I am sure that it's not a problem of the filter cause if I simulate the load
web test with jmeter I haven't this problem, that is, I have a single
session for every sequence of http request.
I think that the problem is how the client (IVR) of my web application keeps
the session (cookies or url rewriting), but this behaviour is quite strange,
why I have this problem only if I use IVR and filter togheter?
Any suggestion?
Thanks,
Enrico.

When starting a new thread (ie sending a message to the list about a
new topic) please do not reply to an existing message and change the
subject line. To many of the list archiving services and mail clients
used by list subscribers this makes your new message appear as part
of the old thread. This makes it harder for other users to find
relevant information when searching the lists.
This is known as thread hijacking and is behaviour that is frowned
upon on this list. Frequent offenders will be removed from the list.
It should also be noted that many list subscribers automatically
ignore any messages that hijack another thread.
The correct procedure is to create a new message with a new subject.
This will start a new thread.

There is also the RequestDumperValve which would list out all the
request headers/parameters/cookies/etc. that tomcat is receiving. See
http://tomcat.apache.org/tomcat-5.5-doc/config/valve.html.
It does have a downside in that it locks you into the system's default
encoding. :-(

Yes maybe yours is the best solution, but I have still the problem that I

because JMeter can handle session cookies? :-)
replace getSession with getSession(false) (and check for null) to
prevent tomat from creating new sessions.

Re: filter increase number of session
Posted by Pid <p...@pidster.com>.
If you getSession() Tomcat looks for a session, and creates a new one if
it can't find one.
It looks for a cookie called JSESSIONID or a url variable ;jsessionid=.
If your voice app client can't handle cookies, and you have not URL
encoded each URL in the app, then a new session will be created each
time the filter processes a request.

Re: filter increase number of session
Posted by David Delbecq <de...@oma.be>.
Looking at code of filter you sent me, i see nothing strange, except
perhaps for the getSession. Do you have the IVR server code? Are ou sure
it is using the container session? If not, that may mean the client does
not care about the sessionid, and the server does not use container
session. The fact it does not create this with jmeter is probably
either because you activate cookies handling in jmeter or gave it an url
containing a sessionid.
Try in your filter to print the cookies client sent and the full request
url, i bet a few cents the IVR client is neither sending a session
cookie, neither providing a rewritten url.

Re: filter increase number of session
Posted by Enrico Giurin <en...@yahoo.it>.
Yes I have that,
I know that in this way if I hadn't a session tomcat makes new one, but If I
had one I keep the old session.
So why for every request I have a new session on the server, and why only
with IVR client and not using Jmeter like client?
Thanks,
Enrico.

Re: filter increase number of session

do you have something like
HttpSession session = ((HttpServletRequest)req).getSession() in your
filter code?
