[Chilli] postauthproxy authentication

[James @ ADSL24]

Happy New Year to you all!

I'm wondering if anyone can help.

We currently have a requirement to use the postauthproxy config option
within coovachilli but I need to know if there is a way to set a
username/password for the HTTP proxy, so we can lock it down on the squid
server to a specified user/pass.

We can't just set squid based on specific IPs as a lot of customers are on
dynamic IPs so we can't track them easily.

Does postauthproxy allow a username/password for the proxy to be specified
in this way, and if so how?

Many thanks

James
