+All the environment variables set by this module are:
+
+HTTPS: can be "on" or "off"
+SSL_VERSION_LIBRARY: The version of the gnutls library
+SSL_VERSION_INTERFACE: The version of this module
+SSL_PROTOCOL: The SSL or TLS protocol name (such as "TLS 1.0" etc.)
+SSL_CIPHER: The SSL or TLS cipher suite name.
+SSL_COMPRESS_METHOD: The negotiated compression method (NULL or DEFLATE)
+SSL_SRP_USER: The SRP username used for authentication.
+SSL_CIPHER_USEKEYSIZE and SSL_CIPHER_ALGKEYSIZE: The number if bits used in the used cipher
+  algorithm. This does not fully reflect the security level since the size of 
+  RSA or DHE key exchange parameters affect the security level too.
+SSL_CIPHER_EXPORT: true or false. Whether the cipher suite negotiated is an export one.
+SSL_SESSION_ID: The session ID negotiated in this session. Can be the same during
+  client reloads.
+
+SSL_CLIENT_V_REMAIN: The number of days until the client's certificate is expired.
+SSL_CLIENT_V_START: The activation time of client's certificate.
+SSL_CLIENT_V_END: The expiration time of client's certificate.
+SSL_CLIENT_S_DN: The distinguished name of client's certificate in RFC2253 format.
+SSL_CLIENT_I_DN: The distinguished name of client's issuer certificate in RFC2253 format.
+SSL_CLIENT_S_AN%: These will contain the alternative names of the client certificate 
+  (% is a number starting from zero). The values will be prepended by "DNSNAME:", 
+  "RFC822NAME:" or "URI:" depending on the type. If it is not supported the value 
+  "UNSUPPORTED" will be set.
+SSL_CLIENT_M_SERIAL: The serial number of the client's certificate.
+SSL_CLIENT_M_VERSION: The version of the client's certificate.
+SSL_CLIENT_A_SIG: The algorithm used for the signature in client's certificate.
+SSL_CLIENT_A_KEY: The public key algorithm in client's certificate.
+SSL_CLIENT_CERT: The PEM-encoded client certificate
+SSL_CLIENT_VERIFY: 
+  whether the client's certificate was verified. (NONE if none was sent, or SUCCESS or FAILED)
+SSL_CLIENT_CERT_TYPE: The certificate type can be X.509 or OPENPGP.
+
+SSL_SERVER_V_START: The activation time of server's certificate.
+SSL_SERVER_V_END: The expiration time of server's certificate.
+SSL_SERVER_S_DN: The distinguished name of the server's certificate in RFC2253 format.
+SSL_SERVER_I_DN: The distinguished name of the server's issuer certificate in RFC2253 format.
+SSL_SERVER_S_AN%: These will contain the alternative names of the server certificate 
+  (% is a number starting from zero). The values will be prepended by "DNSNAME:", 
+  "RFC822NAME:" or "URI:" depending on the type. If it is not supported the value

+SSL_SERVER_M_SERIAL: The serial number of the server's certificate.
+SSL_SERVER_M_VERSION: The version of the server's certificate.
+SSL_SERVER_A_SIG: The algorithm used for the signature in server's certificate.
+SSL_SERVER_A_KEY: The public key algorithm in server's certificate.
+SSL_SERVER_CERT: The PEM-encoded server certificate
+SSL_SERVER_CERT_TYPE: The certificate type can be X.509 or OPENPGP.
