Hi,
There are different techniques depending on the platform you are targeting - are you looking at  Windows , Unix or embedded ?

what do you meant source code? All the broswer sees is HTML, under normal circumstances that nothing is fucked in the server, and i hope this is what you mean mate, the HTML.

This my friend is as simple as fucking a whore, and rather just a short.

Code: (ruby) [Select]

require 'net/http'

url = URI.parse('http://evilzone.org')
req = Net::HTTP::Get.new(url.to_s)
res = Net::HTTP.start(url.host, url.port) {|http|
  http.request(req)
}
puts res.body

Code: (python) [Select]

import requests

r = requests.get('https://evilzone.org')
print r.text

Code: (javascript) [Select]

//Node.js, feel la kenjoe41 baby.
var request = require("request");

var parseHTML = function(html) {
    //parse it anyway you want
};

request("http://evilzone.org", function (error, response, body) {
    if (!error) {
        parseHtml(body);
    } else {
        console.log(error);
    }
});

Code: (D) [Select]

import std.net.curl, std.stdio;

auto content = get("http://evilzone.org");

writeln(content);

* kenjoe41 thinks that is enough.

uhh...?

Do you want to scrape and download the source automatically.. or.. do you want a script to press f12 for you?

For Windows use Wnetwatcher:

Or use AngryIpscanner  (windows, mac, linux)

Feel like this question should have been googled first.
