A number of BBC podcasts set their rss url to http:// instead of https://. One can still get these feeds over https/443 (see below). But podcast apps will try to use http/80 of course.

Why does BBC do this. Or maybe it's the podcast apps that do it. Weird.

"In Our Time" is one example.

   printf 'GET /b006qykl.rss HTTP/1.0\r\nHost: podcasts.files.bbci.co.uk\r\nConnection: close\r\n\r\n' \
   |nc -vvn 125.252.212.113 80 > 1.rss

   printf 'GET /b006qykl.rss HTTP/1.0\r\nHost: podcasts.files.bbci.co.uk\r\nConnection: close\r\n\r\n' \
   |openssl s_client -connect 125.252.212.113:443 -ign_eof > 1.rss
