Question

need to get data from another page

Asked by: bennybutler

My apache server is behind a load balancer that, when using SSL only gives me the IP address of the load balancer, not the client.  When NOT using the SSL I can get the IP address from x-forwarded-for header (or something like that.)  I'm looking for a javascript that I can run on an SSL page that will pull the correct IP off of a non-ssl page.  My non ssl page would only present the IP address, something like

http://www.domain.com/ip.php will be:
<? echo $_SERVER['x-forwarded-for'];?>

And for testing , I just want to alert('$ip') and get the IP address spit out.

Oh, and it shouldn't throw up any "do you only want to view secure parts in the page" errors.
Any ideas?

If your browser supports Java, you can have the Client IP by using the following IP address:

<SCRIPT>
var ip = new java.net.InetAddress.getLocalHost();
var ipStr = new java.lang.String(ip);
document.writeln(ipStr.substring(ipStr.indexOf("/")+1));
</SCRIPT>

Use cookie to transfer it between your ssl and nonssl page.

Already thought about the cookie method, but the customers START OFF on the page that I need to get the IP, and I don't want to redirect them away and back.

I copied the script to a browser and IE and chrome both gave me javascript errors.

I don't know java, but getLocalHost looks like it's getting the machine's IP address.  80% of consumers now are behind NAT, and it's almost always going to give me 192.168.1.x.  I need the IP they originate from, although it would be interesting to have their local IP as well, but not nearly as important.

Did you try the CGI variable "REMOTE_ADDR"

If use java or jscript to get clien ip address, you will always meet some issues like security and compatibilty.
So then, I think you can try flash.

no answer here.

The javascript method only gives the internal network, not their IP on the internet... most people behind a firewall so that's no good.

Remote_addr is the obvious solution, but it's blocked by the load balancer, hence the problem.

Setting with cookie is no good because they start off on an SSL page.  I'm looking for a javascript to pull the data off a non-ssl page, and give it to the SSL version, and NOT give an error, but that may just be impossible.
