'Evening everyone,

  I'm wondering if anyone has already seen a problem like this.

  Background - I'm trying to use stunnel to act as an SSL server and 
redirect connections so that I can use the JMeter script recorder to 
build automated tests for an app's web GUI. (The recorder does not 
support SSL.)

  The software versions are: stunnel 4.15 on i686-redhat-linux-gnu with 
OpenSSL 0.9.8b 04 May 2006

  I'm able to set up the redirection, and everything in the stunnel log 
looks OK - and, this is just making the connection manually - without 
JMeter - but trying to access the target app just hangs in the browser 
with a "connecting to..." status message.

  Here's the stunnel config file that I'm using - the log is attached.

   client=yes
   output=/tmp/stunnel.log
   debug=debug
   [8084]
   accept=hostname:8079
   connect=hostname:8084

  Interestingly - when I kill the stunnel process, the browser displays 
(most of) the target app's top level page.


Thanks in advance,
