[Quickfix-users] Re: [Quickfix-developers] Session Identification Problem

That's a strange scenario.  The way QuickFIX would handle this now is=20
the way you don't want to do it, two separate processes.  The problem=20
with using something like the port to identify the session is twofold. =20=

One, as Joerg pointed out, it is a transport level concept and not one=20=

which the fix protocol itself is familiar with.  Another problem is=20
that the port is not a part of the message.  In other words, in a=20
scenario like this, you can no longer rely on the contents of the=20
message to identify what session it belongs to.  This means we would=20
have to rely on some meta-data in addition to the FIX message itself to=20=

figure out where it needs to be routed.  I don't have a problem with=20
this necessarily, but I don't think and arbitrary attribute like the=20
session port is the way to do it.

One thing I may consider is something along the lines of a UserID=20
configuration field.  Something like this:

[SESSION]
SenderCompID=3DSENDER
TargetCompID=3DTARGET
UserID=3DMARKETDATA

[SESSION]
SenderCompID=3DSENDER
TargetCompID=3DTARGET
UserID=3DORDER

This user id would be optional, and it would at least make the id=20
meaningful.
