我有一个绝对简单的代理在运行。
require 'webrick'
require 'webrick/httpproxy'
s = WEBrick::HTTPProxyServer.new(:Port => 8080,
:RequestCallback => Proc.new{|req,res| puts req.request_line, req.raw_header})
# Shutdown functionality
trap("INT"){s.shutdown}
# run the beast
s.start在我看来,这不会以任何方式影响交流。但是有些网站已经不能正常工作了。特别是http://lastfm.de的嵌入式flash播放器不能正常工作。
标题看起来像是链接:

也许是Lastfm.de上的crossdomain.xml文件?
它设置为仅允许从以下域进行闪存访问:
*.last.fm
*.audioscrobbler.com
87.117.229.54http://lastfm.de/crossdomain.xml

WEBrick阻塞I/O ...这意味着它不能流式传输响应。例如,如果您在youtube页面上查看视频,则在代理下载完所有视频内容之前,该流不会转发到您的浏览器。如果您希望视频在下载过程中在浏览器中播放,则必须寻找像EventMachine这样的非阻塞I/O解决方案。
