Hi All,

Can anyone see a problem with doing (something like) the following, to handle the situation like http://lists.sip-router.org/pipermail/sr-users/2014-October/085251.html?

Admittedly, it is probably a less common use case, but it has been raised several times on the list so I believe it is a genuine one.

Did you try Daniel's advice?

"See msg_apply_changes() from textopsx to get the path header visible."

Did that not work?

The above needs to be repeated in lookup_branches function of same file, but I wanted to check others' opinions first.
