2.CGI variables

CGI server variable	Description
SERVER_SOFTWARE	Name and version of the information server software answering the request (and running the gateway). Format: name/version.
SERVER_NAME	Server's hostname, DNS alias, or IP address as it appears in self-referencing URLs.
GATEWAY_INTERFACE	CGI specification revision with which this server complies. Format: CGI/revision.
SERVER_PROTOCOL	Name and revision of the information protocol this request came in with. Format: protocol/revision.
SERVER_PORT	Port number to which the request was sent.
REQUEST_METHOD	Method with which the request was made. For HTTP, this is Get, Head, Post, and so on.
PATH_INFO	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	Translated version of PATH_INFO after any virtual-to-physical mapping.
SCRIPT_NAME	Virtual path to the script that is executing; used for self-referencing URLs.
QUERY_STRING	Query information that follows the ? in the URL that referenced this script.
REMOTE_HOST	Hostname making the request. If the server does not have this information, it sets REMOTE_ADDR and does not set REMOTE_HOST.
REMOTE_ADDR	IP address of the remote host making the request.
AUTH_TYPE	If the server supports user authentication, and the script is protected, 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, the username the user has authenticated as. (Also available as AUTH_USER.)
REMOTE_IDENT	If the HTTP server supports RFC 931 identification, this variable is set to the remote username 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	Length of the content as given by the client.

GI client variable	Description
HTTP_REFERER	The referring document that linked to or submitted form data.
HTTP_USER_AGENT	The browser that the client is currently using to send the request. Format: software/version library/version.
HTTP_IF_MODIFIED_SINCE	The last time the page was modified. The browser determines whether to set this variable, usually in response to the server having sent the LAST_MODIFIED HTTP header. It can be used to take advantage of browser-side caching.
HTTP_URL	The URL path in an encoded format.

CGI client certificate variable	Description
CERT_SUBJECT	Client-specific information provided by the web server. This data typically includes the client's name, e-mail address, and so on, for example:O = "VeriSign, Inc.", OU = VeriSign Trust Network, OU = "www.verisign.com/repository/RPA Incorp. by Ref.,LIAB.LTD(c)98", OU = Persona Not Validated, OU = Digital ID Class 1 - Microsoft, CN = Matthew Lund, E = mlund@.com
CERT_ISSUER	Information about the authority that provided the client certificate, for example:O = "VeriSign, Inc.", OU = VeriSign Trust Network, OU = "www.verisign.com/repository/RPA Incorp. By Ref.,LIAB.LTD(c)98", CN = VeriSign Class 1 CA Individual Subscriber-Persona Not Validated

判断浏览器是否支持CGI

<cfscript>
       myServer=cgi.SERVER_NAME;
       if (myServer==cgi.SERVER_NAME)
             WriteOutput("Server exists");
       else
             WriteOutput("Server does not exist");
</cfscript>

3.Application and session variables

Application.myvariable 
Session.myvariable

ColdFusion provides the following predefined application and session variables:

Application.ApplicationName  Session.CFID  Session.CFToken  Session.URLToken

但怎么加的参数目前还没明白

最近在做的项目，系统学习并记录下，基本都是官网查看
