- remove "http://"

- I think pathnames in windows are different to *nix.

- again remove "http://"
- these acl are redundant. just one will do. it can be re-used whenevr
needed.

- again redundancy. just one of the two will do.

- the denies above are all redundant without any allows. the "deny all"
directly below them does the same thing, but faster.

Those are the obvious points about general config. Try "squid -k parse" to
see what squid itself thinks of the config.
