ProxyServer

In computer networks, a proxy server is an application that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. Proxies were invented to add structure and encapsulation to distributed systems.

This is an implementation of a Http proxy server application with some fantasy features in python.

Features :

• Logging
  • Logs everything happens to a file.

"logging": {
    "enable": true,
    "logFile": "logFileName.log"
} 

• Restriction
  • If it is enable, it can restrict clients to visit some restricted websites.
  • Also it can notify admin with email in smtp protocol. ( Actually email address and password are hardcoded in code and can be changed)

"restriction": {
    "enable": true,
    "targets": [
      {
        "URL": "www.somewebsite.com",
        "notify": "true"
      },
    ]
  }

• HttpInjection
  • It can show a message in a navbar header for index page of websites.

"HTTPInjection": {
    "enable": true,
    "post": {
      "body": "An Injection Text"
    }
  }

• Accounting
  • If it is enable, it can set a maximum byte usage for every user.

"accounting":{
    "users":[
        {
            "IP": "127.0.0.1",
            "volume":"8000000"
        },
    ]
}

• Privacy
  • With adding a specific user agent you can increase your privacy.

 "privacy": {
    "enable": true,
    "userAgent": "Proxy Server V1.000"
  }

• Caching
  • With enabling this feature proxy can cache some repeated resources and send back again their to client.
  • It uses Http cache system.

"caching": {
    "enable": true,
    "size": 200
}

How to Run :

First of all you should set config file with above features and `proxy port.

Then you can run proxy server with python. It's not uses any specific library and dependecies.

python server.py
