Proxy Checker: Am I Using a Proxy?

Question: Proxy Checker: Am I Using a Proxy?

Strange thing is, I’m NOT USING A PROXY! Never bothered to run the proxy checker when i’m just using the internet normally before. Tried it this time and got these information below. looks like I’m using a proxy.

HTTP_ACCEPT text/xml,application/xml,application/xhtml+xml,text/html; q=0.9,text/plain; q=0.8,image/png,*/*; q=0.5
HTTP_ACCEPT_LANGUAGE en-us,en; q=0.5
HTTP_ACCEPT_CHARSET ISO-8859-1,utf-8; q=0.7,*; q=0.7
HTTP_USER_AGENT Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
HTTP_VIA 1.1 wc-bkkbt2 (NetCache NetApp/5.6.2D7) Dubious
Conclusion You are possibly using a proxy.

So, my question is this…

On sites that don’t like you using Proxies (paypal etc) how dubious to the above values need to be before said sites can confirm you are definately using a proxy and then take action?

Can someone explain the values: HTTP_VIA, HTTP_X_FORWARDED FOR in more detail for me (sorry still new to this game)

Is having these fields pop up on a proxy i’m using going to flag up my paypal account?

Answers to any or all of these questions would be nice!

Answer: You aren’t using any proxy in your computer. But your company or ISP may be using a proxy. So the proxy checker detects proxy using.

Proxy Anonymity

Proxy server may be configured to either reveal or hide the end user’s IP address, depending on the administrator’s preference. Proxy Anonymity is determined by whether or not the proxy reveal your real IP address.

There are three types of proxy server according its anonymity.

High Anonymous Proxy (Level 1): The web server can’t detect whether you are using a proxy by the information your browser sent.
Anonymous Proxy (Level 2): The web server knows that you are probably using a proxy, but it can’t detect your real IP.
Transparent Proxy (Level 3): The web server knows that you are using a proxy and it can also detect your real IP address.

Proxy Checker

Proxy checker analyzes the HTTP header variables. If your IP address is revealed, it will usually show up in the HTTP_X_FORWARDED_FOR variable. Other variables that may reveal your real IP are:

You don’t need to worry about using a proxy. If I was PayPal staff, I would think that you were using a proxy. But I would not think you were going to cheat because both of your IPs ( and were from the same city: Bangkok. It’s usually because your ISP is using a proxy.
