我想将未设置特定 cookie ( c_cntry) 且请求 URL 没有国家值作为路径中的第一个元素的传入请求定向到将尝试找出正确设置的内部服务c_cntry。

但是当我http://localhost:8085/something-to-do在浏览器中发送类似的东西时，我的日志中会出现无休止的递归，最终浏览器中会出现 502 代理错误。日志似乎显示localhost:9999未触及 ProxyPass 指令中给出的内容。

将非常感谢您帮助解决此问题。

#req doesnot have country nor is a good cookie present -- send it for geo-discovery

RewriteCond %{REQUEST_URI} !^/(usa|india)/
RewriteCond %{HTTTP_COOKIE} !u_cntry=(usa|india)
RewriteRule (.*) /GeoDiscover?orig=($1)  [QSA,P]

尝试再添加一个重写条件：

RewriteCond %{REQUEST_URI} !^/GeoDiscover

那么你的重写规则应该如下所示：

RewriteCond %{REQUEST_URI} !^/(usa|india)/
RewriteCond %{REQUEST_URI} !^/GeoDiscover
RewriteCond %{HTTTP_COOKIE} !u_cntry=(usa|india)
RewriteRule (.*) /GeoDiscover?orig=($1)  [QSA,P]

PS您提供 的重写日志-我不认为它是实际的重写日志（至少我之前没有见过提到的格式GET，200响应代码等）。

PPS 在进行重写调试时——更好地使用RewriteLogLevel 9——它会产生更详细的输出（可能太多，所以不能在工作服务器上使用，但它准确地告诉了正在发生的事情）。
