问题描述
最近我不得不迁移一个已有近15年历史的网站，考虑新的URL是
Recently I had to migrate somesite which was nearly 15 years old, consider the new url is
，旧站点为 https://myold.domain.com (内部IP:192.168.1.15 ，在公共领域不可用)
and the old site was https://myold.domain.com (Internal IP : 192.168.1.15, which is not available in public domain)
在旧站点中，它有一个名为"sitefiles"的目录，其中包含许多子文件夹和文件，例如图像，文件等
In old site it was having directory called "sitefiles", in which many sub folders and files like images, files etc
所以我要实现的假设是，如果用户在浏览器上点击了带有白名单扩展名(例如.jpg，.jpeg，.png，.pdf，.doc，.docx，.gif，.svg的文件请求)的URL， )，例如，然后从内部IP服务那些请求
So what I want to achieve is suppose if user hits url on browser which was file request with white listed extensions such (.jpg , .jpeg, .png, .pdf, .doc, .docx, .gif, .svg) say for example, then serve those requests from internal IP
https://mynew.domain.com/sitefiles/events/somedirectory /somefile.jpg
https://mynew.domain.com/sitefiles/somedoc.jpg
请注意sitefiles目录很大，而且它是嵌套的，我不知道该怎么做，目前我尝试的是
Please note sitefiles directory is quite big, and its nested, I don't know how to go about this, currently what I tried is
ProxyPass /sitefiles/ http://192.168.1.15/sitefiles
ProxyPassReverse /sitefiles/ http://192.168.1.15/sitefiles
但是
- 我如何将白名单实际上是对列入白名单的文件的请求?
- 文件的绝对路径对我来说真的是不可预测的，我们可以传递 之类的信息吗?
ProxyPass %{REQUEST_URI} http://192.168.1.15/$1
我也尝试过，在下面一个让我不好的请求下，您的浏览器发送了该服务器无法理解的请求
I also tried, below one which gives me Bad Request your browser sent a request that this server could not understand
RewriteCond %{REQUEST_URI} ^/sitefiles
RewriteRule ^\/?(.*)$ http://192.168.1.15/$1 [P,L]
如果我将[P,L]修改为[R=301,L]，它可以正确地重定向到其他服务器，则不知道相同的原因，
Above same one if I modify [P,L] to [R=301,L] it properly redirecting to other server, not sure why proxy is not working
推荐答案
要允许某些列入白名单的扩展，您可以使用mod_rewrite规则代替ProxyPass:
To allow certain whitelisted extensions you may use mod_rewrite rule instead of ProxyPass:
RewriteEngine On
RewriteRule ^sitefiles/.+\.(?:jpe?g|png|pdf|docx?|gif|svg|pptx?)$ http://192.168.1.15/$0 [L,NC,P]
此规则中的
P标志执行ProxyPass为您执行的操作.
P flag in this rule does what ProxyPass does for you.
这假定mod_proxy已在Apache配置中正确设置.
This assumes mod_proxy is properly setup in Apache config.
