Please stop top-posting.
If you free the slist and then try to append headers to that freed list, you
will most likely get a crash or some other memory related problems, much in
the same way you can't work on memory you free()d already.
If you pass in a NULL pointer as the first argument to curl_slist_append, it
will create/malloc a new list to work on.
