Problem Description:

We have discovered a bug as part of an application migration from CF8 to CF11. In CF8 the 'name' attribute in the CFHTTPPARAM tag may contain special characters (e.g. "|") which are URL encoded when sent to the server when type='url' is used. 

In CF11 this is no longer the case, and using special characters in the name attribute results in the following error CFHTTP Illegal Argument: Illegal character in query at index X.

Steps to Reproduce:

<cfhttp url="">
	<cfhttpparam type="url" name="|" value="">

<cfdump var="#cfhttp#">

Actual Result:

Charset 	[empty string]
ErrorDetail 	Illegal Argument: Illegal character in query at index 23:|=
Filecontent 	Connection Failure
Header 	[empty string]
Mimetype 	Unable to determine MIME type of file.
struct [empty]
Statuscode 	Connection Failure. Status code unavailable.
Text 	YES 

Expected Result:

A standard CFHTTP structure with a 200 Statuscode

Any Workarounds:

It's possible to use URLEncodeFormat to encode the name attribute to work around the issue:

<cfhttp url="">
	<cfhttpparam type="url" name="#URLEncodedFormat("|")#" value="">

<cfdump var="#cfhttp#">
