For a programming exercise ( from Computer Networking: A Top-Down Approach (6th Edition) by Kurose and Ross ), we're trying to develop a simple proxy server in python. We were given the following code, wherever it says #Fill in start. ... #Fill in end. that is where we need to write code. My specific question and attempts will be below this original snippet. We need to start the python server with: python proxyserver.py [server_ip] then navigate to localhost:8888/google.com and it should work when we're finished. from socket import * import sys if len(sys.argv) <= 1: print 'Usage : "python

I'm developing a twitter messaging utility using Twitter API (twitterizer). But since I'm within a corporate proxy, I'm getting the error '407 Proxy Authentication Required'. Is there any way to authenticate the user before calling the API or use the default proxy settings? P.S Internally the API is using HttpWebRequest. This does not answer your question. But the error you are getting is clearly a Proxy authentication error. You might want to either disable or enable the proxy. To disable the proxy, in the App.config file add the following configuration <system.net> <defaultProxy enabled=

I work on a Ubuntu VM in my company's laptop which uses proxy server for connecting to internet. After some research I found out how to install modules using pip install with proxy. For example, using this command I can install my virtualenv module: sudo pip install --proxy=http://user:pass@<proxy_address>:<portnumber> virtualenv However, after creating a virtual environment folder, activate it and then install a module using this pip command: pip install --proxy=http://user:pass@<proxy_address>:<portnumber> pyperclip I get this error: Retrying (Retry(total=4, connect=None, read=None, redirect

问题的来源 从老师那里借了两台服务器跑数据，但是老师的服务器没有公网ip，只有学校内网ip，故只能在实验室或者图书馆登录。有没有什么办法，能让我在宿舍或者家里，远程连接进这两台学校内网的服务器呢？答案肯定的，那就是 反向代理 。前提是，我得有一台有公网ip的服务器（例如，阿里云服务器或VPS都可以）。 什么是代理？ 要搞清楚什么是反向代理，就得知道什么是 代理（Proxy） 。代理其实就是一个跳板。比如我要去图书馆借一本书，我把要借的书的信息写在纸上，交给图书馆管理员，由图书馆管理员去仓库帮我把书取出来交给我。那我们就说，图书馆管理员是我的代理。 在计算机网络中，代理分为 正向代理 和 反向代理 。 正向代理 假如我们访问不了某网站，但是代理服务器可以访问，我们可以让代理服务器去帮助我们访问目标网站，并把结果返回给我们。对于远程目标网站来说，它只得到了一次请求记录，并不知道是我们通过代理服务器访问的，因此正向代理隐藏了我们自身的信息，但也取决于代理服务器告不告诉目标网站。对于我们客户端来说，我自己是知道我使用了代理去访问某个网站的。 总的来说，正向代理是一个位于客户端（client）和原始服务器(origin server)之间的服务器（proxy server）。客户端为了从原始服务器取得内容，向代理发送一个请求并指定目标(原始服务器)

I was using Mechanize module a while ago, and now try to use Requests module. ( Python mechanize doesn't work when HTTPS and Proxy Authentication required ) I have to go through proxy-server when I access the Internet. The proxy-server requires authentication. I wrote the following codes. import requests from requests.auth import HTTPProxyAuth proxies = {"http":"192.168.20.130:8080"} auth = HTTPProxyAuth("username", "password") r = requests.get("http://www.google.co.jp/", proxies=proxies, auth=auth) The above codes work well when proxy-server requires basic authentication. Now I want to know

I'm newbie programmer building a startup that I (naturally) hope will create a large amount of traffic. I am hosting my django project on dotcloud, which is on Amazon EC2. I have some streaming media (Http though, not rmtp) so the dotcloud guys recommended I go with a CDN. I am also using Amazon S3 for storage and so decided to go with Amazon CloudFront as my CDN. The time has come where I need to turn my attention to caching and I am lost and confused. I am completely new to the concept. The entire extent of my knowledge comes from a tutorial I just read ( http://www.mnot.net/cache_docs/ )
