Oleg,
Thanks for the reply.
Actually we would typically like each thread to have its wire trace recorded
into its own file. Let me explain with eg:
Thread 10 will capture wire trace of class A and store the wire trace in
File A
Thread 11 will capture wire trace of class B and store the wire trace in
File B.
Both Thread 10 and Thread 11 will be running simultaneously ofcourse. We
looked into the source code a while back and realized that Wire.java has a
static HEADER_WIRE and CONTENT_WIRE fields and a private constructor. So
could it be that when we do Logger.getLogger("httpclient.wire") in our
constructor both Thread 10 and Thread 11 in the above example are returned
with the same instance of the Wire log and thus causing the logs to get
mixed up?
Currently we run 30 such threads and the output files are a disaster :)
Also, just as an FYI, we are using httpclient 3.x.
