GAppProxy is a great local proxy engine created on GAE(google application engine). G2Proxy aims to extend more functions from GAppProxy. Currently, I'm focus on improve the client proxy program and make it easily to serve for multiple google application instances.

Installation instructions:

when you get the enhanced client proxy program from here, you also need to get GAppProxy, then you simply substitute the old proxy.py in 'local_proxy_x.x.x' folder.

G2Proxy是基于GAppProxy的， 目前， 只改写了其客户端proxy.py， 可以配置支持多个代理托管多个Fetch Server(GAE 应用程序），也可以配置单个代理托管多个Fetch Server, 达到高效利用每个Fetch Server的配额(流量），举例，好处是，你看网上比较大的视频时不会再断断续续了，目前还在进一步改进中。
