URLSessionFormat 733
URLSessionFormat
Description
Depending on whether a client computer accepts cookies, this function does the following:
• If the client does not accept cookies: automatically appends all required client identification
information to a URL
• If the client accepts cookies: does not append information
This function automatically determines which identifiers are required, and sends only the
required information. It provides a more secure and robust method for supporting client
identification than manually encoding the information in each URL, because it sends only
required information, when it is required, and it is easier to code.
Returns
A URL; if cookies are disabled for the browser, client and session data are appended.

Usage
In the following example, the cfform tag posts a request to another page and sends the client

myactionpage.cfm
If the detected cookie is not turned on, or cookie support cannot be reliably detected, the
function return value is as follows:
myactionpage.cfm?jsessionid=xxxx;cfid=xxxx&cftoken=xxxxxxxx

<cfform
method="Post"
