What is the difference between a servlet and a proxy servlet (or in short what does proxy mean in this context)? servlet和代理servlet之间有什么区别（或者简言之，代理在这个上下文中意味着什么）？ How/Why routing backend calls though a proxy servlet, instead of http calls, in AJAX/Javascript helps resolving cross domain issues? 如何/为什么在AJAX / Javascript中通过代理servlet而不是http调用来路由后端调用有助于解决跨域问题？

As far as I know, ProxyServlet is the one which does not serve the request by itself but seeks another resource (possibly in the same war/different war/even different machine). 据我所知，ProxyServlet不是自己提供请求而是寻求另一种资源（可能在相同的战争/不同的战争/甚至不同的机器上）。 However, the calling client is unaware of this delegation. 但是，调用客户端不知道此委派。

HTTP Proxy Servet is a nice example of ProxyServlet HTTP Proxy Servet是ProxyServlet的一个很好的例子
