<cfset "client.cfid#client.CFID#.cftoken#client.CFToken#.username" = "">
<cfset "client.cfid#client.CFID#.cftoken#client.CFToken#.password" = "">


The #'s signs are used to grab the variable values.  
If you place <CFOUTPUT></CFOUTPUT> tags around the variable, then you can view the value.

<CFOUTPUT>
#client.CFID#
</CFOUTPUT>  

If you want to view the value of the above two set statements :

<CFOUTPUT>client.cfid#client.CFID#.cftoken#client.CFToken#.username</CFOUTPUT>

Actually its an interesting bit of code. It defines a unique username and password variable.

Possible for authentication/authorization.

The reason that the # is needed is becuase it is within double quotes.

You could get the same result with the following code:

<cfset Client["cfid" & client.CFID & ".cftoken" & client.CFTOKEN & ".username" = "">
<cfset Client["cfid" & client.CFID & ".cftoken" & client.CFTOKEN & ".password" = "">

It is NOT setting a cookie.  It is setting a client variable.

So if client.CFID = 12 and Client.CFTOKEN = 1T67YA85 then you actually have the statements

<cfset Client.cfid12.cftoken1T67YA85.username = "">
<cfset Client.cfid12.cftoken1T67YA85.password= "">

Personally I am not sure why you would go to this trouble of such a complex variable name for a user's username and password.  There are much simpler ways to make usique username and password variables without having so many layers deep.  And it would be very messy to use later in your pages....
