cfhttp - Object moved

Guys, I have a doubt with the CF 11.

When put that way chttp CF 11 returns, while making a dump the "Object moved" message

<cfhttp url="http://site.com.br/email/envia.cfm" method="post" charset="utf-8">

     <cfhttpparam type="url" name="IdCodigo" value="#qMaxID.IdCodigo#">

     <cfhttpparam type="url" name="EmaInt" value="#val(arguments.EmaInt)#">

     <cfhttpparam type="url" name="tipo" value="3">

</cfhttp>

And so it works normally.

<cfhttp url="site.com.br/email/envia.cfm?IdCodigo=#qMaxID.IdCodigo#&EmaInt=#val(arguments.EmaInt)#&tipo=3" charset="utf-8"></cfhttp>

He had no problems in CF9, but now the 11 is so.

Anyone know what's going on?

Thanks
