Hello,

I'm using this example to make a SSL connection: http://fm4dd.com/openssl/sslconnect.htm. Now I want to also acess a HTTPS proxy. Is there a way to acess a HTTPS proxy with the OpenSSL library?

Any tip will be very helpful,
Thanks.

See http://wiki.squid-cache.org/Features/HTTPS and http://tools.ietf.org/rfc/rfc2817.

AFAIK OpenSSL does not provide specific support for SSL via proxy, but you can set up a SSL connection using the CONNECT request to the proxy.

Using a proxy for SSL connection does not make sense if you want to take advantage of a proxy's caching feature, since these CONNECT requests cannot be cached. This is by design.

Using a proxy for SSL can be useful if you want to avoid NAT, or want to log, or filter, the connection targets.

Hope this helps,
Ted
