This is my first post to this mailing list, so please tell me, if I posted this the wrong place, or I in any other way should do something different. I have been playing around with Webrick for some time now, and decided to set up a virtual machine with a hosted webrick based application. For every request, the request goes through two Apache proxies because of lack of IP adresses. The forwarded hostname is therefore split by commas like this: Host= domain.com, someotherdomainoorip.com Webrick doesnt handle this well. It looks like it only supports one single forwarded hostname. This can however easily be fixed by changing like 291 in httprequest.rb from: host, port = @forwarded_host, @forwarded_port To: host, port = @forwarded_host.split(",")[0].strip, @forwarded_port If not, Webrick will not handle the request and raise an error. My fix may be more than a hack than a fix, but for now it works and makes Webrick actually handle the request instead of crashing. I have attached a .diff I made with Subversion. Thank you for a great programming language. -- Kasper Johansen -- http://redmine.ruby-lang.org
