HOW TO DEFINE OWN HEADER FIELDS WITH APACHE 2

With your own header fields, you actually can't do real sense-making things, but isn't it really cool,
if your server has its own header field?

If you visit a page on this server, let's say spheniscida.de, the apache httpd sends the additional header field

	X-Spheniscida-original: yes

(Test it with following URL: http://quixapp.com/headers/?r=http%3A%2F%2Fspheniscida.de%2F )

But now let's talk about the actual realization of this feature.

First make sure that you're running a apache2 httpd on your machine (I really don't know whether this directive runs with apache 1.x!)

Then look in your apache configuration directory (usually /etc/apache2). If there's a apache2.conf, use this file, if there's only a httpd.conf, then
you have to use httpd.conf. 

Open the file with your favourite editor (I prefer vim), and append a line like the following (I use this line to add the X-Spheniscida-Original-Field):

	Header set X-Spheniscida-original "yes"

You see, the configuration is really simple. The formal syntax is:

	Header set <FIELD NAME> "<FIELD CONTENT">

If you add your headers, keep in mind that it is *very* good to choose a name with "X-" at the beginning, so the visting browsers know
that you're using non-standardized headers. And please don't use a field with one of the following names:

	Accept-Ranges
	Age
	Allow
	Cache-Control
	Connection
	Content-Encoding
	Content-Language
	Content-Length
	Content-Location
	Content-MD5
	Content-Disposition
	Content-Range
	Content-Type
	Date
	ETag
	Expires
	Last-Modified
	Link
	Location
	P3P
	Pragma
	Proxy-Authenticate
	Refresh
	Retry-After
	Server
	Set-Cookie
	Strict-Transport-Security
	Trailer
	Transfer-Encoding
	Vary
	Via
	Warning
	WWW-Authenticate

Of course you may use this header fields if YOU REALLY KNOW WHAT YOU DO! This fields are standardized and it's better
to only let the server use this names.
