Using the Request.ServerVariables Object

Request.ServerVariables Object:

The ServerVariables Object has many properties besides the 'LOGON_USER'. Here is a list of all of the properties and their uses:

AUTH_TYPE: The authentication method that the server uses to validate users when they attempt to access a protected script.

CONTENT_LENGTH: The length of the content as given by the client.

CONTENT_TYPE: The data type of the content. Used with queries that have attached information, such as the HTTP queries POST and PUT.

GATEWAY_INTERFACE: The revision of the CGI specification used by the server. Format: CGI/revision.

HTTP_: The value stored in the header HeaderName. Any header other than those listed in this table must be prefixed by 'HTTP_' in order for the ServerVariables collection to retrieve its value.

LOGON_USER: The Windows NT® account that the user is logged into.

PATH_INFO: Extra path information as given by the client. You can access scripts by using their virtual path and the PATH_INFO server variable. If this information comes from a URL it is decoded by the server before it is passed to the CGI script.

PATH_TRANSLATED: A translated version of PATH_INFO that takes the path and performs any necessary virtual-to-physical mapping.

QUERY_STRING: Query information stored in the string following the question mark (?) in the HTTP request.

REMOTE_ADDR: The IP address of the remote host making the request.

REMOTE_HOST: The name of the host making the request. If the server does not have this information, it will set REMOTE_ADDR and leave this empty.

REQUEST_METHOD: The method used to make the request. For HTTP, this is GET, HEAD, POST, and so on.

SCRIPT_MAP: Gives the base portion of the URL.
