Nice, meaty answer. Thanks.
Is this a decent way to output them, or is there something more
elegant that skips the array conversion? (I'm not terribly familiar
with structures yet.)
<cfscript>
aryCGI = StructKeyArray(cgi);
for (i=1; i LTE arrayLen(aryCGI); i=i+1) {
cgiKey = aryCGI[i];
cgiVal = evaluate(aryCGI[i]);
if (len(cgiVal)) {
writeoutput(cgiKey & '=' & cgiVal & '<br>');
}
}
</cfscript>
Thanks,
Jamie
