X-Forwarded-For - How to get

[Monty808]

Hi,

Normally I use env['REMOTE_ADDR'] to get the IP address. But..on
webfaction using wsgi...I have to use X-Forwarded-For to get the IP
address.

So...what is the code to get the IP address?

Thanks

Try using web.ctx.ip. If that doesn't work, try web.ctx.env['HTTP_X_FORWARDED_FOR'].

web.ctx.env['HTTP_X_FORWARDED_FOR'] wat is this?

Here is the repsonse from webfaction that will explain the issue....

> I have two sites running.  One is a static/cgi/php site and the other is a

All requests to your sites are proxied from the front-end web server to
another server internally. So, when the request reaches your app, it's
actually coming from the internal IP 127.0.0.1.

When the request is proxied, the original IP is stored in the X-Forwarded-For
header.

Static/CGI/PHP sites are proxied to our shared Apache+PHP environment. That
environment uses an Apache module to masquerade X-Forwarded-For as
REMOTE_ADDR.

Your other apps do not use that module, so if you need to check IP for those
apps (like a mod_wsgi site) then you need to look at X-Forwarded-For.

Hope that helps!
