Mod rewrite httpd2.2使用带有RewriteCond的反向代理进入无限循环

我想引导没有特定cookie集（

c\u cntry

）且请求URL没有国家/地区值作为路径中的第一个元素的传入请求，该请求将尝试找出

c\u cntry

的正确设置

但是当我发送类似

http://localhost:8085/something-待办事项

在浏览器中，我的日志中出现了无休止的递归，最终浏览器中出现了502代理错误。日志似乎显示未触及ProxyPass指令中给出的

localhost:9999

非常感谢您帮助解决这个问题

httpd.conf

RewriteLogLevel 3

RewriteRule .*\.php$ - [L]

#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]

ProxyRequests Off
ProxyPreserveHost On
ProxyTimeout 5
ProxyPass /GeoDiscover http://localhost:9999/GeoDiscover connectiontimeout=1 timeout=3 retry=3

尝试再添加一个重写条件：

RewriteCond %{REQUEST_URI} !^/GeoDiscover

那么您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]

p.S. 您提供的重写日志——我不认为它是实际的重写日志（至少我以前没有看到过提到

GET

，

200

响应代码等的格式）

p.p.S.

在执行重写调试时——最好使用

RewriteLogLevel 9

——它会产生更详细的输出（可能太多，因此无法在工作服务器上使用，但它会准确地告诉正在发生的事情）。

嗨，L.O.，感谢您的帮助
我错误地认为，在应用[L]规则后，它将自动通过代理设置。它并没有做到这一点（非常令人困惑，我仍然需要弄清楚）。因此，我所做的是（I）将[L]改为[N]，并（ii）按照您的建议预先设置[P]规则。所以现在看起来是这样的：
#规则0
重写规则（^GeoDiscover）（|/.*）$[QSA，P]
这很好。我相信ProxyPassReverse仍然有效。谢谢Dinesh
PS：日志是真实的！
