Who is responsible to passing information from a client request to CGI variables (Apache?). We use IBM Tivoli Access Manager and it basically pre-authenticates all users and sets a variable in the HTTP header iv-user. I can than see on Apache that the variable is "rewritten ?" to HTTP_IV_USER.
CGI specification
Protocol-Specific Meta-Variables
The server SHOULD set meta-variables specific to the protocol and
scheme for the request. Interpretation of protocol-specific
variables depends on the protocol version in SERVER_PROTOCOL. The
server MAY set a meta-variable with the name of the scheme to a
non-NULL value if the scheme is not the same as the protocol. The
presence of such a variable indicates to a script which scheme is
used by the request.
Meta-variables with names beginning with "HTTP_" contain values read
from the client request header fields, if the protocol used is HTTP.
The HTTP header field name is converted to upper case, has all
occurrences of "-" replaced with "_" and has "HTTP_" prepended to
give the meta-variable name. The header data can be presented as
sent by the client, or can be rewritten in ways which do not change
its semantics.

Thank you. The linked post indeed helps but now the question would be how does the server set them?
