I used an older #2616 when working on this, rather than the current

https://www.rfc-editor.org/info/rfc6266

since that came out in 2011 -

2006-01-22 (2.8.6dev.17)
* modify parsing of filename from Content-Disposition so that the name is not
  truncated on embedded whitespace.  For most systems, the blanks will be
  retained.  For VMS and MSDOS, the blanks are translated to underscores
  (Debian #291716) -TD

but even still, it's supposed to work -

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=291716

Perhaps a test-url to experiment with would be helpful.

A default "http" redirects to "https", as seen in a (Lynx) trace:
