var http = require('http');
var urls = process.argv.slice(2);
var responses = process.argv.slice(2);
var completedReqests = 0;


for (var i=0; i < urls.length;i++){
    http.get(urls[i],(function (i){ 
        return function(response){
            var webData = '';
            response.setEncoding('utf8');
            response.on('data', function(data){
                webData = webData + data;
            });
            response.on('error',console.error);
            response.on('end',function(){
                responses[i] =webData;
                completedReqests++;
                if (completedReqests === urls.length){
                    console.log(responses.join('\n'));
                }
            });
        };
    })(i));
}

//     var http = require('http')
//     var bl = require('bl')
//     var results = []
//     var count = 0

//         console.log(results[i])
