Reqstrict

Reqstrict is rule based forward proxy server. It restricts only HTTP (and not HTTPs) requests based on certain rules as configured by the user.

Motivation

Reqstrict is created to ease down the process of configuring proxy server. The user is expected to modify script in order to manage the proxy server.

Installation

$ git clone https://github.com/gophergala2016/reqstrict.git
$ cd reqstrict
$ go get github.com/yuin/gopher-lua
$ go build
$ ./reqstrict

Usage

In order to use reqstrict as your proxy server, you first need to configure proxy settings of your browser. You can do it by following steps for Chrome and Firefox

./reqstrict -b [bindaddress] -p [port] -f [scriptfile] -m [maxconnection]
  -b string
    	The proxy server's bind address (default "0.0.0.0")
  -f string
    	The path of the lua script file (default "rule.lua")
  -m int
    	Maximum connections to proxy server (default 20)
  -p int
    	The proxy server's port (default 8000)

You can configure rules in rule.lua

for example, if you want to block http://www.google.com, then simply put function as :

  function filter (request)
    if string.find(request,"google") then
      return false
    else
      return true
    end
  end

Similarly you can block requests coming from certain User-Agents also.

Note : Do not change the function name or return type (true or false).
