[Documentation] The new Squid Wiki is close to be finished

Hi all, i´am close to finish the Squid wiki http://wiki.ipfire.org/nonpublic/de/configuration/network/proxy and it might be great if you all could overview it for faults or extensions. The only area which aren´t complete is the authentication http://wiki.ipfire.org/nonpublic/de/configuration/network/proxy/configuratio... . So i only made the local authentication cause i have no experience with the rest. It might also be great if someone can finish this section.

If this wiki was going to be corrected and checked, i will step then to the english translation.

Greetings to all

Erik
