I would like to test the 7.0-alpha, but for internet-access I need an external proxy with port-number, user and password.
I think this is possible in the actually 6.01-Version.
Would this be available in the 7.0-Version again?
How can I configure this in 7.0-alpha without the server-console?
6.x only has support for an anonymous parent cache - there is on mechanism to provide a username and password for the upstream cache.
To configure 7.0 alpha to use a parent cache, do:
config set SquidParent x.x.x.x
config set SquidParnentPort nnn
signal-event proxy-update
If you do need to authenticate to your upstream cache, then you will need to create a custom template, and add
"login=user:password" to the cache-peer line in squid.conf.
