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:

    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.

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

    Variable

    Description

    HTTP_REFERER

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

    HTTP_USER_AGENT

    The browser 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. 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.
