Some DESY/XFEL internal websites can only be accessed from the internal network. One way to reach them from outside is to use a local proxy with an SSH connection, created like this:
ssh -D 22222 [email protected]
The proxy.pac file in this repository tells your browser to use this proxy for a specific list of sites. It's a specific list so you can leave it in place when you're not running the ssh proxy. It will only affect sites that you can't reach without the proxy anyway.
You can use it by configuring this URL in your proxy settings:
https://github.com/European-XFEL/desy-proxy-config/raw/master/proxy.pac
E.g. in Firefox:
You may also be able to clone the repository and use a file:// URL (tested in
Firefox).
This only works with the SSH proxy command above. You need a DESY account to make the SSH connection.
