It has been a few months since my last blog post and reason for that is the lack of time and of course – my laziness:)
Here we will talk about an interesting Mozilla Firefox Add-on and the whole concept around the X-Forwarded-For header.
The X-Forwarded-For is a HTTP header which is used by proxies to identify an IP address of a client. If you use internet through a proxy and you try a service to show your internet IP address (showip.net), it is not very pleasent to see your local address in the result – at least not to me.
As a Firefox user I have discovered a very nice and useful add-on for X-Forwarded-For header. In the X-Forwarded-For value box you can type more than one IP address and those IP addresses will be displayed in the X header.
