If Windows, see the rw-FAQ Q2.19.

Otherwise, see ?download.file and choose a different download method, or look at the source code (src/modules/internet/nanohttp.c) and submit a patch.

BTW, the chooseCRANmirror() function does not do HTTP: download.file() and url() do and the help is at ?download.file.
