You could check out YQL if you don’t want to write the server side code yourself… Here’s an example that I wrote kinda quickly, so there’s no error handling and possibly things could be done in a better way. But I won’t spend any more time on it tonight It should at least give you an idea about how to use it…


<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Scraping</title>
</head>

<body>
<form action="">
	<div>
		<label for="url">URL</label>
		<input id="url" name="url" type="url" />
		<input type="submit" value="Get content" />
	</div>
</form>
<div id="result"></div>

<script>
var Scraper = (function () {
	var callbackIndex = 0;

	function createCallback(callback, currentScript) {
		callbackIndex += 1;
		var callbackName = "c" + callbackIndex;
		Scraper[callbackName] = function (data) {
			var content = "";
			if (data.results) {
				content = data.results[0];
			}
			callback(content);

			document.body.removeChild(currentScript);
			delete Scraper[callbackName];
		};
		return "Scraper." + callbackName;
	}

	function get(url, callback) {
		var query = "select * from html where url = '" + url + "'",
			src = "",
			s = document.createElement("script"),
			callbackName = createCallback(callback, s);

		src = "http://query.yahooapis.com/v1/public/yql?q=" + encodeURIComponent(query) + "&format=xml&callback=" + callbackName;
		s.setAttribute("src", src);
		document.body.appendChild(s);
	}

	return {
		get: get
	};
}());

(function () {
	var form = document.getElementsByTagName("form")[0];
	form.onsubmit = function () {
		var res = document.getElementById("result");
		res.innerHTML = "Loading...";

		Scraper.get(this.url.value, function (content) {
			res.innerHTML = "<pre>" + content.replace(/</g, "<") + "</pre>";
		});

		return false;
	};
}());
</script>
</body>
</html>

Hmmm thx, now i just want to know if it’s possible, can i execute
document.cookie="pid=2);
so that it will show a page that requires that cookie?

so run a command that sets cookie for site and then runs the innerhtml?
