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).
The Cookies collection Retrieves the values of the cookies sent in an HTTP request. For example, suppose the page
reads a cookie called "readMe" on the user’s system. On the server, the values of the cookie are stored in the variable
Request.Cookies("readMe").
The ClientCertificate collection Retrieves the certification fields from the HTTP request sent by the browser. The
certification fields are specified in the X.509 standard.
