I finally got this to work using the following:
Created a new message using the following:
set newmsg [msgcreate -recover -class protocol -type data $httpBody]
msgmetaset $newmsg DESTCONN $HciConnName PRIORITY 5120 SOURCECONN $HciConnName
I then used the OVER disposition to send this message back to the inbound queue of this thread:
lappend dispList “OVER $newmsg”
This seems to work OK. Thanks for the assistance!
