看起来这个域正在主动阻止curl（和wget）请求，如果你传递一个浏览器的UserAgent，你可以解决这个问题（curl和wget使用相同的用户代理命令行参数）。例如：

这不起作用：

C:\>wget http://www.segundamano.es/anuncios-madrid/
  SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc
  syswgetrc = C:\Program Files (x86)\GnuWin32/etc/wgetrc
  --2013-10-16 10:06:13--  http://www.segundamano.es/anuncios-madrid/
  Resolving www.segundamano.es... 195.77.179.69, 213.4.96.70
  Connecting to www.segundamano.es|195.77.179.69|:80... connected.
  HTTP request sent, awaiting response... 502 Bad Gateway
  2013-10-16 10:06:15 ERROR 502: Bad Gateway.

但这样做：

C:\>wget --user-agent="Mozilla/5.0 (Windows NT 5.2; rv:2.0.1) Gecko/20100101 Firefox/4.0.1" http://www.segundamano.es/anuncios-madrid/
  SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc
  syswgetrc = C:\Program Files (x86)\GnuWin32/etc/wgetrc
  --2013-10-16 10:06:29--  http://www.segundamano.es/anuncios-madrid/
  Resolving www.segundamano.es... 195.77.179.69, 213.4.96.70
  Connecting to www.segundamano.es|195.77.179.69|:80... connected.
