The following table lists the most common CGI variables created by the browser and passed to the server:
Variable Description
SERVER_SOFTWARE The name and version of the information server software
answering the request (and running the gateway). Format:
name/version.
SERVER_NAME The server's hostname, DNS alias, or IP address as it appears in self-
referencing URLs.
GATEWAY_INTERFACE The revision of the CGI specification to which this server complies.
Format: CGI/revision.
SERVER_PROTOCOL The name and revision of the information protocol this request
came in with. Format: protocol/revision.
SERVER_PORT The port number to which the request was sent.
REQUEST_METHOD The method with which the request was made. For HTTP, this is
Get, Head, Post, and so on.
PATH_INFO The extra path information, as given by the client. Scripts can be
accessed by their virtual pathname, followed by extra information
at the end of this path. The extra information is sent as PATH_INFO.
PATH_TRANSLATED The server provides a translated version of PATH_INFO, which
takes the path and does any virtual-to-physical mapping to it.
SCRIPT_NAME A virtual path to the script being executed; used for self-
referencing URLs.
QUERY_STRING The query information that follows the question mark (?) in the
URL that referenced this script.
REMOTE_HOST The hostname making the request. If the server does not have this
information, it sets REMOTE_ADDR and does not set
REMOTE_HOST.
REMOTE_ADDR The IP address of the remote host making the request.
AUTH_TYPE If the server supports user authentication, and the script is
protected, this is the protocol-specific authentication method
used to validate the user.
REMOTE_USER AUTH_USER If the server supports user authentication, and the script is
protected, this is the user name they have authenticated as. (Also
available as AUTH_USER.)
REMOTE_IDENT If the HTTP server supports RFC 931 identification, this variable is
set to the remote user name retrieved from the server. Use this
variable for logging only.
CONTENT_TYPE For queries that have attached information, such as HTTP POST
and PUT, this is the content type of the data.
CONTENT_LENGTH The length of the content as given by the client.
