Re: Known apps supporting tls max frag size extn

> Also, I have lost the url of a website which used to analyze any given server ( eg www.yahoo.com) for its supporting various tls extensions. You provide the server url and it will display all the tls extns supported by that server.  If you know of any such url, could you please help me with that also.

openssl s_client has an argument -tlsextdebug:

$ openssl s_client -connect www.yahoo.com:443 -tlsextdebug

TLS server extension "renegotiation info" (id=65281), len=1
