[SR-Users] append_branch and t_replicate issue

[Bruce McAlister]

Just an update on this, it appears to send 2 REGISTER requests in 
parellel to BACKUP_REGISTRAR_3, so it looks like the append_branch is 
being added but its uri is set to BACKUP_REGISTRAR_3 (and not 
BACKUP_REGISTRAR_2 as requested int the append_branch section)
