TLSv1 support compression with gzip/deflate that can provide for a lot of protocols a great improvement (just think about SIP/TLS or IMAP) in terms of bandwidth. Currenly Python SSL stack based on OpenSSL doesn't allow the configuration (enabling/disabling/forcing) of TLS compression. This ticket is about suggesting to implement TLS compression configuration of OpenSSL as described on: http://blog.dave.cridland.net/?p=73

So, there are two things here: - allow to disable compression (it's enabled by default AFAICT) using the SSL_OP_NO_COMPRESSION flag - allow to query compression status on SSL sockets using the SSL_get_current_compression() API

Here is a patch.

(note that some OpenSSLs are built without compression, such as Mageia's)
