OK. I will try that and get back to you with the results...

I am not very familiar with what the DEBUGFUNCTION supplies because I never
had to use it. However, if it is the same info output by the verbose mode
then maybe it is too much over head if you want just to be *informed* of the
URLs that are visited. I was thinking more along the lines of a
curl_easy_getinfo() option which returns a linked list of visited URLs. The
way I see it this information could very well be retrieved after the fetch
rather than during it.

OTOH, I can imagine a scenario where someone might want to keep track of
redirections during the fetch and decide to cancel the fetch based on that
info.

For me both ways are OK and not much problem to implement on my app side.
However, I guess the DEBUGFUNCTION way would be easier to code inside
libcurl.

Yes, you could say that. But for the SSL problem there is a workaround (or a
better way of doing it, depends on the way you look at it I guess) through
using EGD sockets or /dev/rand both of which don't exist on Win32. For the
redirection URLs, you are right, it is needed in libcurl on all platforms.
