问题 I am new to haproxy (actually proxy'ing in general) and I can't figure out how to add a path to my backend. I have my backend defined as: server server1 ns.foo.com:7170 check I want to add /web such that the request is directed to https://ns.foo.com:7170/web. Thanks, Mark 回答1: What you need is HTTP rewriting https://www.haproxy.com/doc/aloha/7.0/haproxy/http_rewriting.html#rewriting-http-urls Adding this to your backend should solve your problem: acl p_root path -i / http-request set-path

Using app.set to set trust proxy

由 假如想象 提交于 2020-03-04 06:47:28
问题 When setting the application variable trust proxy , does the second argument in app.set mean that the server trusts all the requests FROM 127.0.0.1 or TO 127.0.0.1? For example: app.set('trust proxy', 'loopback'); // or app.set('trust proxy', '127.0.0.1'); and then var sess = { proxy: true cookie: { httpOnly: true, secure: true } } According to the documentation, several types of value are allowed as the second argument: Boolean If true, the client’s IP address is understood as the left-most

NodeJs mirror website proxy

由 半世苍凉 提交于 2020-03-03 07:15:20
问题 How would you write a server that simply mirrored a website when a request was received? For example, hitting http://localhost:5000 which is running NodeJS would render cnn.com with images and everything. Is this called a passthrough proxy? I'm not looking for something that requires configuring an actual proxy within your browser settings, but instead just serves up essentially a mirror of another site by passing the requests through. 回答1: First, let me make sure I understand your question.

Limit Apache Proxy upload speed per connection/ip?

由 亡梦爱人 提交于 2020-03-02 11:58:51
问题 I looked at mod_bandwidth and mod_cban but they dont seem to satisfy my requirements. I am running a proxy server with apache 2.2 (mod_proxy, proxy_http, proxy_connect). I want to limit the "upload speed of the client". This is at the same time server download bandwidth, which should not limited. I want it per connection or even better per IP. To make it understandable: The use case is that I don't want bad people uplaoding bad data to bad places using my proxy server to "mask" themselves. Of

代理模式&动态代理

由 折月煮酒 提交于 2020-03-02 08:20:10
动态代理的用途: 动态代理的用途与装饰模式很相似，就是为了对某个对象进行增强。所有使用装饰者模式的案例都可以使用动态代理来替换,动态代理可以更好的解耦合 增强有3个手段 1. 继承 被增强对象不能变 增强内容不能变 2. 装饰者模式 被增强对象可变 但增强内容不能变 3. 动态代理 被增强对象可变 增强内容也可变 如何实现动态代理? 定义一个接口Interface, 被增强的对象的类都会实现这个接口 public interface Interface { public void fun(); } 实现这个Interface接口: 而这个InterfaceImpl就是动态代理中被增强的内容 public class InterfaceImpl implements Interface { @Override public void fun() { System.out.println("目标方法调用"); } } 定义一个接口Advice, 增强内容的类都会实现这个接口 这个接口有两个未实现的方法: before()前置增强的方法 after()后置增强的方法 public interface Advice { public void before(); public void after(); } 而实现了Advice接口的对象就是动态代理中增强内容 JavaAPI: java
