Basicly I told you my thoughts, they are not crystal clear. I was more going
for some kind of dicsussion around different concepts in order to work out
the best solution for most people.

Yeah, but it would also change how it works today and add general confusion I

I would indeed welcome some more voices regarding this, but I won't hold my
breath for it. I'm quite used to silence as input.

Well, if we play with the idea of adding another callback for it, what would
it provide? An 'info-type' (GETTING_THIS_URL for this case) and a 'void
*data' (pointing to the full URL libcurl is about to fetch?) that could
provide various types of informations at various points in the libcurl
Such a callback could also possibly be used by sending "progress-info" at
various stages in a transfer to allow UI-based programs to get to know how
far a particular transfer has reached in its progress etc.
