> When you pass multivalued parameters to org.apache.cocoon.transformation.IncludeTransformer, like:
>    <ci:parameter name="foo" value="bar"/>
>    <ci:parameter name="foo" value="baz"/>
> only the last gets passed in the request made by IncludeTransformer. This is because parameters are stored in a Map.
> HTTP specifies that multi-valued parameters are possible, or rather it does not forbid them. So the query-string "?foo=bar&foo=baz" is perfectly legal.
> The patch changes the way IncludeTransformer handles this case, so that multi-valued parameters are handled correctly. The NetUtils.parameterize() method, used by IncludeTransformer, was already prepared for this.
