Setting the CGI Variable dialog box options

Setting the CGI Variable dialog box options

This dialog box defines ColdFusion CGI variables.

To define a ColdFusion CGI variable:

  1. In the Name text box enter the name of the variable.

    For example, if you want to access the information in the CGI.HTTP_REFERER variable, enter HTTP_REFERER.

    The following table lists the most common ColdFusion CGI variables that are created on the server:




    The name and version of the information server software answering the request (and running the gateway). Format: name/version.


    The server's hostname, DNS alias, or IP address as it appears in self-referencing URLs.


    The revision of the CGI specification to which this server complies. Format: CGI/revision.


    The name and revision of the information protocol this request came in with. Format: protocol/revision.


    The port number to which the request was sent.


    The method with which the request was made. For HTTP, this is Get, Head, Post, and so on.


    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.


    The server provides a translated version of PATH_INFO, which takes the path and does any virtual-to-physical mapping to it.


    A virtual path to the script being executed; used for self-referencing URLs.


    The query information that follows the question mark (?) in the URL that referenced this script.


    The hostname making the request. If the server does not have this information, it sets REMOTE_ADDR and does not set REMOTE_HOST.


    The IP address of the remote host making the request.


    If the server supports user authentication, and the script is protected, this is the protocol-specific authentication method used to validate the 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.)


    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.


    For queries that have attached information, such as HTTP POST and PUT, this is the content type of the data.


    The length of the content as given by the client.

    The following table lists the most common CGI variables created by the browser and passed to the server:




    The referring document. This is the document that linked to or submitted form data.


    The browser the client is currently using to send the request. Format: software/version library/version.


    The last time the page was modified. This variable is sent at the discretion of the browser, usually in response to the server having sent the LAST_MODIFIED HTTP header. It can be used to take advantage of browser-side caching.

  2. Click OK.

    The CGI variable appears in the Bindings panel.
