Hi Arvind,

A few checks
1) Does your CA authorities certifcate contains the certificate that
the host server is presenting you ??
2) What is the exact error you are getting ??

Second part of your query:-
1) There is a call back function in libcurl that may allow you to do
whatever you like with the certificate presented by the host server.
I haven't used it -> CURLOPT_SSL_CTX_FUNCTION. Probably this is what
may help you.
