Hi Brian,
Have you copied the flowscript code literally? The variable uri is not defined. Replace it by a
string literal or pass a uri parameter to the function from the sitemap..
HTH,

I've added your code and I keep getting an error:

generator 'file' at [unknown location]
Any idea why?

You could do it easily with flow-script:
<map:match pattern="foo">
<map:aggregate element="someparts">
<map:part element="ext"
src="cocoon:/getthistroughflow"/>
</map:aggrate>
</map:match>
<map:match pattern="getthistroughflow">
<map:call function="post2requestUri"/>
</map:match>
in flow:
function post2requestUri{
var queryString = "";
for (var i in cocoon.getParameterNames){
queryString += loop through paramters and put them in
querystring
}
cocoon.sendPage(uri+queryString) ;
}
In fact, pretty lousy solution but probably works just fine
