Re: RE: [PHP] HTTP_X_FORWARDED_FOR?
On Thursday 10 January 2002 19:36, [EMAIL PROTECTED] stuffed this into my
mailbox:
Please note that not all proxies will fill in HTTP_X_FORWARDED_FOR. Some will
obscure it others will not fill it in at all, either due to privacy or to
conseal things.

REMOTE_ADDR contains the IP of the computer that requested your page. If it was a proxy doing the request, you'll have the proxy's IP in this variable, and the IP of the computer that requested the page from the proxy will be in HTTP_X_FORWARDED_FOR. This means the best way to grab an IP is with a a function like this: I'm unsure what happens with multiple proxies, and I'd be interested to know - do you get an array of HTTP_X_FORWARDED_FORs? Do you just get the first or the last?

Yeah, I've tried that and the $HTTP_SERVER_VARS but I keep getting this error: PHP Warning: Undefined index: HTTP_X_FORWARDED_FOR in C:\Web\byenighte\phpinfo.php on line 2 I'm using the recommended php.ini, by the way.

Re: [PHP] HTTP_X_FORWARDED_FOR?
Okay, thanks. 'Cause I mean, the REMOTE_ADDR is still there. So you mean that the HTTP_X_FORWARDED_FOR isn't working while I'm working localhost?

This has something to do with the way you access the machine - x-forwarder-for contains the private ip address of your client machine when calling the php pages through a proxy. It has nothing to do with your php or server side configuration. henning -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] HTTP_X_FORWARDED_FOR?
Hi, I just installed IIS 5.0 and PHP 4.1.1 on Win 2000, and I'm wondering what happened to the HTTP_X_FORWARDED_FOR? I doesn't seem to exist on my system. Is it just a variable that needs to be changed, or has it been removed from PHP? Thanks.

[PHP] HTTP_X_FORWARDED_FOR
On php.net I found this: When you use REMOTE_ADDR for getting the IP of the current user, sometimes you get the IP of the ISP Cache server. When this happens, the HTTP_X_FORWARDED_FOR is also set, it contains the IP of the user. [...] Note that the X-Forwarded for header might contain multiple addresses, comma separated, if the request was forwarded through multiple proxies. [...] My question is: If the X-Forwarded for header contains multiple addresses, comma separated, where do I find the one of the user? (I which order does it contain the adresses?) Do I get the right order (from the last proxies (at the beginning) to the user itself (at the end)) when I do this: $ip_route = $HTTP_SERVER_VARS["REMOTE_ADDR"] . "," . $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]; So that I finally have a chronological sorted list (i know: a string that contains the comma seperated ip-addresses of the users way to me (if they were forwarded by the proxie))? Am I right? Thanks for any coments about this. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
