<p>lookup function has an optional uri param for looking up based on that param.<br>
lookup_to_dset is used if we don't want to overwritte the Request-URI but there is option to lookup based on a uri.</p>

<p>during tests i noticed that the append_branch was being called when i did a lookup_to_dset("location", "$fu") and kamailio exited because of that.</p>

<p>i made the append_branch to depend on the _mode ( 0 = lookup ) which seemed to fixed.</p>
