1. it's called the HTTP header - not the CGI header
CGI is an application startup protocol, not a transmission protocol.

See many previous posts of mine (and others). HTTP is a very simple
protocol - it's just ascii character data, eg: here is a request:
GET /somedirectory/somefile.html HTTP/1.1
Host: someserver:8000
Accept: image/jpeg image/gif text/html *
CRLF
where CRLF is a carriage-return followed by a line-feed (ascii 10-13
I think, perhaps the other way round I can never remember).

A servlet cannot examine the HTTP headers that are transmitted - the
servlet container (or servlet engine) has already read them and put
them in the Enumeration.
Since doing what you want to do is rare it's better that the
container read the header (otherwise all servlets would have to read
the header all the time whoch would be silly).
There is also stuff in the header which is relevant to the container
only, for example: persistent connection notification stuff. If the
container didn't read the header it wouldn't be able to act on this.
The solution to your problem is to get a packet sniffer and place it
between your client and your server. You will be able to see the
request being made in clear ascii.
