[R-pkg-devel] URL of a frame (or a vignette)?

  ????? What's the difference between


https://cran.r-project.org/package=bssm/vignettes/bssm.pdf


  ????? and


https://cran.r-project.org/web/packages/bssm/vignettes/bssm.pdf


  ????? When I tried the former, it automatically changed to the latter.
Is the former considered to be more stable?

CRAN puts this on every package page:

"Please use the canonical form https://CRAN.R-project.org/package=xxxx 
to link to this page."

I think one of the checks will complain if it notices you give the link 
in a different form.  I forget which URLs it checks.
