# NOTE!  This pattern does not catch the modern type of MSN filetransfers
# because they use the same TCP connection as the chat itself.  See 
# ../example_traffic/msn_chat_and_file_transfer.txt for a demonstration.

# This pattern has been tested and seems to work well.  It, does,
# however, require more testing with various versions of the official
# MSN client as well as with clones such as Trillian, Miranda, Gaim,
# etc.  If you are using a MSN clone and this pattern DOES work for you,
# please, also let us know.

# First part matches the older MSNFTP: A MSN filetransfer is a normal
# MSN connection except that the protocol is MSNFTP. Some clients
# (especially Trillian) send other protocol versions besides MSNFTP
# which should be matched by the [ -~]*.

# Second part matches newer MSNSLP:

# This part is untested.
