nginx：配置 proxy_pass 时出现问题

我正在将 Web 应用程序从 apache 转换为 nginx。在 apache 的 httpd.conf 中，我有：

ProxyPass /proxy/ http://
ProxyPassReverse /proxy/ http://

这个想法是客户端发送这个 url：

http://web-server-domain/proxy/login-server-addr/loginUrl.php?user=xxx&pass=yyy

Web 服务器调用：

http://login-server-addr/loginUrl.php?user=xxx&pass=yyy

我的 nginx.conf 附在下面，但它无法正常工作。目前它似乎正在调用服务器，但返回应用程序错误。这看起来很有希望，但任何调试它的尝试都失败了！我无法跟踪任何调用，因为 nginx 拒绝将它们放在错误文件中。此外，在登录服务器上放置 echo 语句也无济于事，这很奇怪。

nginx 文档对此没有什么帮助。

关于如何配置 proxy_pass 有什么建议吗？

谢谢！

好的，我在我的 nginx 测试平台上尝试了这个，并在日志中得到以下内容：

2011/08/29 22:35:31 [error] 10074#0: *1257 no host in upstream "", client: 10.103.0.9, server: localhost, request: "GET /proxy/ya.ru HTTP/1.1", host: "10.110.0.42"

因此，nginx 并不是一个合适的工具，因为无法在运行时定义上游主机。
