Define ColdFusion server variables
1. Open the Bindings panel (Window > Bindings). In the Server Variable dialog box, enter the name of the server variable, and click OK.
2. Click the Plus (+) button and select the server variable from the pop-up menu.
3. Enter the name of the variable, and click OK. The ColdFusion server variable appears in the Bindings panel.
The following table lists the built-in ColdFusion server variables:
Variable Description
Server.ColdFusion.ProductName ColdFusion product name.
Server.ColdFusion.ProductVersion ColdFusion version number.
Server.ColdFusion.ProductLevel ColdFusion edition (Enterprise, Professional).
Server.ColdFusion.SerialNumber Serial number of currently installed version of ColdFusion.
Server.OS.Name Name of operating system running on the server (Windows XP,
Windows 2000, Linux).
Server.OS.AdditionalInformation Additional information about installed operating system (service
packs, updates).
Server.OS.Version Version of installed operating system.
Server.OS.BuildNumber Build number of installed operating system.
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.
4. Specify the variable in the collection that you want to access, and click OK.
For example, if you want to access the information in the Request.ServerVariables("HTTP_USER_AGENT") variable, enter the argument
HTTP_USER_AGENT. If you want to access the information in the Request.Form("lastname") variable, enter the argument lastname.
The request variable appears in the Bindings panel.
