Blue Coat?

[Djin]

As I was viewing my PHP $_SERVER variables, I've noticed this:
[HTTP_X_BLUECOAT_VIA] => 00F5E9FC7ACFBCA9

Anyone have an idea what it is?

Also, when I used a web proxy (CGI Proxy) to view the $_SERVER vars, it disappeared.

I was wondering if I can use it to block users who use web based proxies to view my site.

Thanks for any input.

dont know what it is - am sure interested

I do know that blue coat the company specialize in content scanning of web services - so maybe its something to do with that.

Generally, any time a header contains an "X" (any server variable that begins with HTTP was sent as an HTTP header with the request for your script) it means that it is an application specific header, which you won't generally see. A quick Google search for Bluecoat revealed Blue Coat Systems http://www.bluecoat.com, which makes firewall hardware. Are you, perhaps, accessing your site from work when you see that variable? It looks like your request probably passed through a BlueCoat device.

So I guess it has nothing to do with the server I'm hosted on. Oh well, it was worth a shot.
