Hi everybody !
Thanks to all of you for your replies. Unfortunately (or fortunately) I
spent the whole morning trying to reproduce the problem but everything
works fine today!
@Filippo: Ciao! There are no "strange" or blank character on cookie
value, it's just the JSESSIONID "as is". It's a value generated by
Tomcat, isn't it?
@Marcos: I have no logs... I tried to log this morning using log4j at
DEBUG level, but, as I said in the beginning, everything works fine today...
@Christopher: here's the access logs, with all the HTTP calls
(everything's fine, these are NOT the logs of the fail scenario):

I'll explain you our flow:
we call the servlet Automation that starts a thread who sequentially
calls all the other servlets, when the thread has finished the control
is returned to Automation servlet.
Not all servlet are called by thread: lots of them are invoked because
the previous servlet returned an HTML page containing frames that have a
servlet URL in the src attribute. Let's make an example:
Automation --> Thread started --> Call servlet 1 --> HTML is returned
--> Call servlet 2 (it's in the HTML page) --> Thread end --> Automation
Usually the problem occours when invoking servlet from the HTML page
(servlet 2 in the example above, servlet called GetFiltro in the access
logs).
Things I've tried to do:
- increase size of connector input stream buffer, from 2048 to 4096,
using bufferSize attribute
- force the "Set-Cookie" attribute in every response, forcing the
JSESSIONID cookie
If you want I have the entire HTTP headers of request/response.
I'll try again to reproduce the problem, I will send you more details
when it will occour again.
Thanks everybody!
Best regards
