Hi I'm running squid on Ubuntu Gutsy (2.6.14). I'm getting problems
with SSL connections intermittently, I'm wondering what SSL options
should be setting in squid.conf and if there any best practices. My
conf has the following values which is basically the default Ubuntu
vaules. Should we be setting anything for:

https_port,
ssl_unclean_shutdown
ssl_engine
sslproxy_client_certificate
sslproxy_client_key
sslproxy_version
sslproxy_cipher
sslproxy_cafile
sslproxy_capath
sslproxy_flags
sslpassword_programn

Could there be any other obvious reason for SSL request failing intermittently?
