Hello,

On executing the following command,
curl -v https://www.tvg.com

I am getting the message at the end
curl: (52) Empty reply from server

* About to connect() to www.tvg.com port 443 (#0)

I searched curl-users archive regarding this type of reply and I found the
following thread that mentions about "Unpatched client and patched OpenSSL
server"
http://curl.haxx.se/mail/archive-2010-12/0004.html
I tried to follow the description in the above URL, which refers to
http://www.openssl.org/docs/ssl/SSL_CTX_set_options.html#Unpatched_client_and_patched_Ope

As mentioned in the above URL, I do not know how to set the parameter
"SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION"
Could anyone of you please help me how to set this parameter, if this is
the solution or suggest an alternative way of solving the problem.

I tried executing the same curl command with other https website and I am
getting a non-empty response.

On executing the following command in my system,
openssl version
I am getting the following output
OpenSSL 1.0.0e-fips 6 Sep 2011

Please help.

Thanks,
Ajay
