A PAC file is a fancy java script file which allows you to make additional choices as to when you would like to use a Proxy.

How do I prevent Authentication Loops? Does Squid cache authentication lookups? Are passwords stored in clear text or encrypted? Can I use different authentication mechanisms together?

Can I use more than one user-database? References Authentication in interception and transparent modes Can I write my own authenticator? How does Proxy Authentication work in Squid? If the header is present, Squid decodes it and extracts a user credentials. The user agent browser receives the reply and then attempts to locate the users credentials. Sometimes this means a background lookup, sometimes a popup prompt for the user to enter a name and password.

The name and password are encoded, and sent in the Authorization header for subsequent requests to the proxy. However, base64 is a binary-to-text encoding only, it does NOT encrypt the information it encodes.

This means that the username and password are essentially "cleartext" between the browser and the proxy. Therefore, you probably should not use the same username and password that you would use for your account login. Authentication is actually performed outside of main Squid process. When Squid starts, it spawns a number of authentication subprocesses.

This technique allows you to use a number of different authentication protocols named "schemes" in this context. When multiple authentication schemes are offered by the server Squid in this caseit is up to the User-Agent to choose one and authenticate using it. By RFC it should choose the safest one it can handle; in practice usually Microsoft Internet Explorer chooses the first one it's been offered that it can handle, and Mozilla browsers are bug-compatible with the Microsoft system in this field.

In addition to the well known Basic authentication Squid also supports the NTLM, Negotiate and Digest authentication schemes which provide more secure authentication methods, in that where the password is not exchanged in plain text over the wire.Enter squid in the search bar and click search or scroll down until the squid package listing is visible.

Hard disk cache size in MB : Set this as needed, but keep it a reasonable size. Memory cache size: The amount of RAM that squid should claim for caching. Use as much as can be spared, as this is much faster than caching to disk.

Hard disk cache location: The directory where the cache will be stored. If using a non-default location enter it here. Minimum object size: Can be left at 0 to cache everything, but may be raised if small objects are not desired in the cache. Maximum object size: Objects larger than this setting will not be saved on disk. If speed is more desirable than saving bandwidth, this should be set to a low value.

Proxy Interface s : Select which interface s the proxy will listen on. LAN is probably the desired setting.

Allow users on interface: If this is checked, the subnets for the interfaces selected in the last step will automatically have access. There will be no need to add them on the Access Control tab.

Proxy Port: Leave this as There is no need to change the port number for the transparent proxy to work. The remaining settings may be left at their defaults, or changed if desired. It is likely best to leave them alone until the proxy is operational and tested. If any other subnets will pass through the proxy aside from the subnet for the interface squid is using, enter them here.

I really dont care about what package is used as long as the issue can be resolved. FW Rule that allows access external to Reverse Proxy server. FW rule then looks like this. More testing to come here regarding interfaces needed to be involved. Morte testing to come here as well.

Reverse HTTP port Mappings setup not sure if this is needed at this moment. So more testing here as well is needed. Redirects not setup at the moment. I guess this is needed to ensure that i can translate example photo. If anyone has a tip here. Please share.
