I find it interesting that Lynx cannot verify the certificate of
'realclearpolitics.com' (without the www) because the server is
not returning the certificate chain. But with the www is a completely
different server which does have a valid certificate.
Anyway I have found that links (the chain) will display the web site
correctly by default, but gets denied if I supply any one (or more)
of the following options:
-http-bugs.no-compression 1
-http-bugs.http10 1
-http.fake-user-agent Lynx
So as far as Lynx (the cat) is concerned, what we need to do in order
to visit this site is (a) change the user agent, and (b) enable HTTP 1.1.
Enable HTTP 1.1 can be done either in the Options screen or in lynx.cfg.
User agent can be done either in Options or on the command line. My
experimentation shows that they want at least your OS in the user agent,
so "Lynx (Linux 5)" works, while Lynx's default user agent does not
because it doesn't contain the OS name.
