Do you use chunked transfer? Could you attach a *minimal* version of CGI script 
that
reproduces the problem?

Intercepted the error.

Stracing the mongoose process i see when i close the remote window a SIGPIPE 
signal.

The problem is that the signal will not be sent to the cgi itself.

And thus the cgi continues writing on STDOUT but not over the net due to the 
problem
that the window was closed and mongoose detaches the cgi from the net 
connection.

Is it possible to let mongoose pass the KILL -PIPE signal or whatever signal 
comes to 
the real cgi instead of throwing it to dev null?

I don-t know if this is the real problem but sending the same PIPE to the script
the cgi works ok.

This works even in Apache.

I-ll attach a simple text file that simulates the persistent.

just put it in a directory where you can exec cgi and from a 
remote browser call the cgi directly, every 5 seconds it changes the 
number of seconds via remote script.

When you clode the window/tab of the browser the mongoose receives a PIPE
signal but mongoose does not send the PIPE to the responsible of the socket.

Mongoose now sends SIGTERM signal to the CGI process at the end of every CGI 
session.
The change is http://code.google.com/p/mongoose/source/detail?r=262
It leaves Windows version broken, which will be fixed in subsequent CL.

Perfect, straced the process, a little bit slow, it has a 2-3 seconds of 
timeout but
it's OK, it send's
a TERM to the right process(probed with multiple process active).

Many thanks.

This work is SUPER.

Change http://code.google.com/p/mongoose/source/detail?r=263 cleanes up Window 
version.

As for slowness, this is not Mongoose's fault.
Mongoose cannot determine that client has closed the connection until it tries 
to
write something back to the client. And your CGI script performs writes at 5 
second
intervals, hence the delay. Reduce it in your script, and Mongoose will react 
faster.

Marking as fixed.

Found another problem with IE any version....
The persistent connection detaches itself but it dies... immediatly.

With apache this does not happen and i don't know how to debug...

It might be interesting to see what versions of IE misbehave. There are lots of
problems with 8.0, such as not running Flash. Make this a new bug report, since 
this
one is marked Fixed.
