[R-pkg-devel] Invalid URLs in Description Due to Redirection

[Dr. rer. nat. Michael Thrun]

Clicking on the link (https://www.deepbionics.org/) it redirects correctly on my PC.  
If I understand Uwe correctly,
this is an issue with the setting of my hosting provider meaning to change the setting 301 to something else. 
Can someone be so kind to point out to me the right option for a correct redirection from the point of view of CRAN?
I have the choices
301, 302, Proxy, Frameset and URL anchor
and would tend to select frameset, but then only http instead of https is possible.
