The following table lists the built-in ColdFusion server variables:
Define a ColdFusion local variable
Local variables are variables created with the CFSET or CFPARAM tag within a ColdFusion page. The defined local
variable appears in the Bindings panel.
❖ In the Local Variable dialog box, enter the name of the local variable and click OK.
Define ASP server variables
You can define the following ASP server variables as sources of dynamic content: Request.Cookie ,
Request.QueryString , Request.Form , Request.ServerVariables , and Request.ClientCertificates .
1 Open the Bindings panel (Window > Bindings).
2 Click the Plus (+) button, and select Request Variable from the pop-up menu.
3 In the Request Variable dialog box, select one of the following request collections from the Type pop-up menu:
The QueryString collection Retrieves information appended to the sending page’s URL, such as when the page has
an HTML form using the GET method. The query string consists of one or more name-value pairs (for example,
last=Smith , first=Winston ) appended to the URL with a question mark ( ? ). If the query string has more than
one name-value pair, they are combined with ampersands ( & ).
The Form collection Retrieves form information included in the body of the HTTP request by an HTML form using
the POST method.
The ServerVariables collection Retrieves the values of predefined environment variables. The collection has a long
list of variables, including CONTENT_LENGTH (the length of content submitted in the HTTP request, which you can
use to see if a form is empty), and HTTP_USER_AGENT (provides information about the user’s browser).
For example, Request.ServerVariables("HTTP_USER_AGENT") contains information about the submitting
browser, such as Mozilla/4.07 [en] (WinNT; I) , which denotes a Netscape Navigator 4.07 browser.
For a complete list of ASP server environment variables, see the online documentation installed with Microsoft
Personal Web Server (PWS) or Internet Information Server (IIS).
