[openssl-dev] Known apps supporting tls max frag size extn

[Jitendra Lulla via openssl-dev]

Hi,

Could anybody please help me in finding known standard apps ( eg browsers and 
servers) which support tls extension for maximum fragment size negotiation?


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.

Thanks
Jitendra

openssl s_client has an argument -tlsextdebug:

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