Dirk and Daniel,

Thanks a lot for your suggestions.

Our application has been relying on libcurl for URL redirection. We would
need to rewrite a large portion of the code to handle URL redirection
manually.

Daniel, do you see a problem with extending libcurl in either of the
approach I suggested? I don't really mean: "I don't want to change my code,
so I will just mess around with libcurl". It is just that the extension to
libcurl seems pretty simple. So I suggested it.
