Apache在无限循环中运行，请求URI太长

Question

我想从cookie中读取一个值，并将该值作为查询字符串传递，为此我使用了以下规则

**1 : "RewriteCond %{HTTP_COOKIE} !^preferenceLocale=([^;]+) [NC] 
RewriteRule ^/*(.*) http://192.168.132.148/cs/Satellite?pagename=YBWrapper&ybdomain=%{HTTP_HOST}&ybpage=$1&%{QUERY_STRING} [P]"**
if cookie value is available then i need to execute fallowing set of condition and rule,  
**2 :"RewriteCond %{HTTP_COOKIE} preferenceLocale=([^;]+) [NC]
RewriteRule ^/*(.*) http://192.168.132.148/cs/Satellite?pagename=YBWrapper&ybdomain=%{HTTP_HOST}&ybpage=$1&preferred_locale=%1&%{QUERY_STRING} [P]"**

这些规则单独运行很好，但如果两个规则都被放置，则其失败并出现错误Request UIR太长，

如果我们看到日志，HTTP_HOST将被一些垃圾值替换

Answer 1

U只需要给出一个条件，然后对Cookie进行必要的重写。

删除"无cookie"重写的条件。首先放置有条件的重定向，而不是不带条件的重定向。

 if cookie value is available then i need to execute fallowing set of condition and rule,  
**2 :"RewriteCond %{HTTP_COOKIE} preferenceLocale=([^;]+) [NC]
RewriteRule ^/*(.*) http://192.168.132.148/cs/Satellite?pagename=YBWrapper&ybdomain=%{HTTP_HOST}&ybpage=$1&preferred_locale=%1&%{QUERY_STRING} [P]"**

 RewriteRule ^/*(.*) http://192.168.132.148/cs/Satellite?pagename=YBWrapper&ybdomain=%       {HTTP_HOST}&ybpage=$1&%{QUERY_STRING} [P]"**

Answer 2

如果规则和代理的目标位于同一主机上，则每次都会应用这些规则。例如：

1. 传入请求，应用规则
2. 没有preferenceLocale cookie，已附加查询字符串
3. URL被发送到要代理的mod_proxy
4. mod_proxy提出请求
5. 从步骤1开始重复

这就是为什么查询字符串不断重复自己的原因，并注意到在第二个到最后一个实例之后，ybdomain=参数是如何从test100.fwqae148.yelladworks.in变为192.168.132.148（您要代理的IP）的。这种情况会继续发生，因为cookie preferenceLocale或其缺失会传递给每个代理请求，因此对cookie的检查将始终为真。

您需要添加一些条件来检查查询字符串，这样它就不会再次代理请求：

RewriteCond %{HTTP_COOKIE} !preferenceLocale=([^;]+) [NC] 
RewriteCond %{QUERY_STRING} !pagename=YBWrapper
RewriteRule ^/*(.*) http://192.168.132.148/cs/Satellite?pagename=YBWrapper&ybdomain=%{HTTP_HOST}&ybpage=$1&%{QUERY_STRING} [P]
RewriteCond %{HTTP_COOKIE} preferenceLocale=([^;]+) [NC]
RewriteCond %{QUERY_STRING} !pagename=YBWrapper
RewriteRule ^/*(.*) http://192.168.132.148/cs/Satellite?pagename=YBWrapper&ybdomain=%{HTTP_HOST}&ybpage=$1&preferred_locale=%1&%{QUERY_STRING} [P]
