Excellent. Just what I needed. Thanks a lot!
One question though:
The NSHTTPURLResponse allHeaderFields dictionary contains keys like: “Content-Length” and “Last-Modified”.
Are these standardized or might other sites use other keys like “Modification-Date” or “Nbr-of-Bytes” ?
Kind regards,
Gerriet.
