Hello,
r-uri itself is a branch. Practically, an append_branch() in
request_route is adding a new destination in addition to r-uri address.
Maybe you can explain why lookup("location") is not working for you, as
it is updates the branch for r-uri as well as adds the other contacts as
extra branches.
You may want to set a branch flag when processing the REGISTER to know
that it is a websocket. Then, you can test the same branch flag in
branch_route to discover if the destination is over websocket or not.
Cheers,
Daniel
