URLEncodedFormat(string [, charset ])

URLDecode; "Tags and functions for globalizing" in Chapter 17, "Developing Globalized Applications," in ColdFusion MX Developer's Guide

ColdFusion MX 6.1: Changed the default encoding to be the response character encoding.

ColdFusion MX: Added the charset parameter.

URL encoding formats some characters with a percent sign and the two-character hexadecimal representation of the character. For example, a character whose code is 129 is encoded as %81. A space is encoded with a plus sign.

Query strings in HTTP are always URL-encoded.

<h3>URLEncodedFormat Example</h3>
<cfif IsDefined("url.myExample")>
   <p>The url variable url.myExample was passed from the previous link ... 
   its value is:
   <br><b>"<cfoutput>#url.myExample#</cfoutput>"</b>
</cfif>
<p>This function returns a URL encoded string.
<cfset s = "My url-encoded string has special characters & other stuff">
<p> <A HREF = "urlencodedformat.cfm?myExample=<cfoutput>#URLEncodedFormat(s)#
</cfoutput>">Click me</A>
