[Box-Admins] I need Help (was Re: Squeak Wiki Problem)

I have been debugging the reported problems accessing the wiki.squeak.org wiki for those behind a proxy. I have tracked it down to the implementation of HttpRequest>>initProxyForwarding in the image. It assumes that if an x-forwarded for header exists that it is a single IP address. This appears to be a poor assumption. For example:

x-forwarded-for: 74.141.6.178, 62.90.138.162

I have not so far been able to track down documentation to confirm whether or not this is 'officially' valid. Nonetheless Swiki should probably not fail when this assumption is invalid.
