no_proxy?(dest) click to toggle source

The documentation around the format of the no_proxy variable seems inconsistent. Some suggests the use of the * as a way of matching any hosts under a domain, e.g.:

*.example.com

Other documentation suggests that just a leading '.' indicates a domain level exclusion, e.g.:

.example.com

We'll accommodate both here.

   # File lib/puppet/http/proxy.rb
37 def self.no_proxy?(dest)
38   no_proxy = self.no_proxy
39   unless no_proxy
40     return false

44     begin
45       dest = URI.parse(dest)
46     rescue URI::InvalidURIError
47       return false
48     end
49   end
50 
51   no_proxy.split(/\s*,\s*/).each do |d|
52     host, port = d.split(':')
53     host = Regexp.escape(host).gsub('\*', '.*')
54 
55     #If this no_proxy entry specifies a port, we want to match it against
56     #the destination port.  Otherwise just match hosts.
57     if port
58       no_proxy_regex  = %r(#{host}:#{port}$)
59       dest_string     = "#{dest.host}:#{dest.port}"
