Perfect compatibility of the major browsers to obtain Http_referer methods to summarize _javascript skills

Later checked some relevant data, found in IE through window.location.href or is not able to get http_referer, really do not understand IE browser, a lot of browsers run very good things, it is not supported, finally there is no way, PHP can only forge the source Http_referer method or use JS to forge.

IE can be identified by the Http_referer commit is triggered by the click of the event or form form submitted by the request, the following is based on the online data summarized a method:

<script>
function Referurl (URL) {
var isie= (document.all)? True:false;
if (Isie) {
var Linka = document.createelement (' a ');
Linka.href=url;
Document.body.appendChild (Linka);
Linka.click ();
}
else window.location = URL;

var url= "http://www.jb51.net";
Referurl (URL);
</script>

This method first uses document.all to determine whether the current browser is IE, if it is a link, and then automatically execute the onclick event, if not the words will use JS jump. So you can get http_referer in the process page.

This method is tested via IE, Firefox, Safari, and Chrome

2. PHP uses curl to forge IP and routing http referrer

referer.php

<?php
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, "http://mydomain.com/ip.php");
curl_setopt ($ch, Curlopt_httpheader, Array (' x-forwarded-for:8.8.8.8 ', ' client-ip:8.8.8.8 ')); Construct IP
curl_setopt ($ch, Curlopt_referer, "http://www.jb51.net/");  Tectonic antecedents
curl_setopt ($ch, Curlopt_header, 1);
$out = curl_exec ($ch);
Curl_close ($ch);

Echo $out;

ip.php

<?php
function Getclientip () {
if (!empty ($_server["Http_client_ip"))
$ip = $_server["Http_ Client_ip "];
else if (!empty ($_server["http_x_forwarded_for"]))
$ip = $_server["Http_x_forwarded_for"];
else if (!empty ($_server["REMOTE_ADDR"]))
$ip = $_server["REMOTE_ADDR"];
else
$ip = "err";
return $ip;
}
echo "IP:". Getclientip (). "<br>";
echo "Referer:". $_server["Http_referer"];
