CGI/1.1 Compliance

The list of environment variables that gophor sets are as follows.

RFC 3875 standard:

# Set
GATEWAY INTERFACE
SERVER_SOFTWARE
SERVER_PROTOCOL
CONTENT_LENGTH
REQUEST_METHOD
SERVER_NAME
SERVER_PORT
REMOTE_ADDR
QUERY_STRING
SCRIPT_NAME
SCRIPT_FILENAME

# NOT set
    Env Var     |                  Reasoning
----------------------------------------------
PATH_INFO       | This variable can fuck off, having to find the shortest
                | valid part of path heirarchy in a URI every single
                | CGI request so you can split and set this variable is SO
                | inefficient. However, if someone more knowledgeable has
                | other opinions or would like to point out where I'm wrong I
                | will happily change my tune on this.
PATH_TRANSLATED | See above.
AUTH_TYPE       | Until we implement authentication of some kind, ignoring.
CONTENT_TYPE    | Very HTTP-centric relying on 'content-type' header.
REMOTE_IDENT    | Remote client identity information.
REMOTE_HOST     | Basically if the client has a resolving name (not just
                | IP), not really necessary.
REMOTE_USER     | Remote user id, not used as again no user auth yet.

Non-standard:

# Set
SELECTOR
DOCUMENT_ROOT
REQUEST_URI
