I mean get_redirects() function adds (internally) a new branch (from the 
contact of the 3xx reply). And you take its value (via $ds), do whatever 
you do with it, and add it again from script (append_branch) -> you have 
2 branches...

This in my opinion on this piece of script, but there is also the chance 
I'm missing something here...I haven't tried it ;)

Bogdan
