[英]Apache rewrite request using a different forward proxy
I would like to forward a request in Apache, based on a request header, to a different forward proxy. 我想基于请求标头将Apache中的请求转发给不同的转发代理。 I think the best would be to use mod_rewrite, but it can use only a reverse proxy defined in the same apache configuration.
我认为最好的方法是使用mod_rewrite,但它只能使用在相同的apache配置中定义的反向代理。
I also checked the ProxyRemote property of mod_proxy but it can't be used based on conditions, only based on request url's. 我还检查了mod_proxy的ProxyRemote属性,但它不能根据条件使用,只能基于请求url。
I need something like: 我需要这样的东西:
If X-CUSTOM-HEADER is value-1 -> forward request to forward proxy p1 If X-CUSTOM-HEADER is value-2 -> forward request to forward proxy p2 如果X-CUSTOM-HEADER是值-1 - >转发请求转发代理p1如果X-CUSTOM-HEADER是值-2 - >转发请求转发代理p2
etc. 等等
Din anyone managed to make something like this? Din有人设法制作这样的东西吗?
Thanks, Alin 谢谢,艾琳
I found a solution, its not really elegant. 我找到了一个解决方案,它不是很优雅。 It involves some adaptation on the second server as well.
它还涉及第二台服务器上的一些调整。
It derives from a project where I had a similar problem, but needed the servers to be "fully" (selected by a custom script that uses database resources). 它源于我遇到类似问题的项目,但需要服务器“完全”(由使用数据库资源的自定义脚本选择)。
This should at least work (I run my URL through a rewrite map to modify it, I adapted it to use headers using RewriteCond
). 这应该至少有效(我通过重写映射运行我的URL来修改它,我使用
RewriteCond
调整它以使用标头)。
# example for server number "5" in your remote proxy network
RewriteCond %{HTTP:X-CUSTOM-HEADER} 1
RewriteRule http://([a-z0-9\.]+)/(.*) http://$1.5.server.yourdomain.com$1 [P]
ProxyRemoteMatch .*\.5\.server\.yourdomain\.com.* http://5.server.yourdomain.com:80
You basically adapt the URL so it is a subdomain of your second server, then you strip it out again. 您基本上调整了URL,使其成为第二台服务器的子域,然后再将其剥离。
This part goes on the second (remote proxy server): 这部分继续第二个(远程代理服务器):
<ProxyMatch "http://.*\.[0-9]+\.server\.yourdomain\.com/.*">
RewriteEngine on
RewriteRule (proxy:http[s]?://.+)\.[0-9]+\.server\.premiumize\.me(.+) $1$2
... your code ...
</ProxyMatch>
Try this: 试试这个:
# Prevents Apache from functioning as a forward proxy server (where you don't want)
ProxyRequests Off
# Preserve Host in http protocol on destination server
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
# enable rewrite engine
RewriteEngine On
# check header
RewriteCond %{HTTP:X-CUSTOM-HEADER} 1
# execute forward proxy
RewriteRule (.*) http://server1/$1 [P,L,QSA]
# check header
RewriteCond %{HTTP:X-CUSTOM-HEADER} 2
# execute forward proxy
RewriteRule (.*) http://server2/$1 [P,L,QSA]
you should be able to achieve it by using the RewriteCond directive verifying with %{HTTP:header}. 你应该能够通过使用%{HTTP:header}验证的RewriteCond指令来实现它。
Try the following: 请尝试以下方法:
RewriteEngine On
RewriteCond %{HTTP:X-CUSTOM-HEADER} 1
RewriteRule (.*) http://p1.example.com$1 [P]
ProxyPassReverse / http://p1.example.com
RewriteCond %{HTTP:X-CUSTOM-HEADER} 2
RewriteRule (.*) http://p2.example.com$1 [P]
ProxyPassReverse / http://p2.example.com
Hope it helps. 希望能帮助到你。 :)
