iRule to Restrict access based on JSON Parameter Value

Hi all,

I need to restrict access to the application based on the values of two JSON parameters in payload of POST request.

My JSON looks similar to spinet below:

{
	"parameter1":null,
	"parameter2":"stringX",
	"contentType":"application/json",
	"parameter3":"stringY",
	"timeStamp":"{{todayDate}}",

My goal is to allow request to be forwarded to the pool only when "parameter2" equals "stringX" and "parameter3" equals "stringY". In all other cases I need to RST the connection.

I only have LTM (v13.1) at my disposition.

Had anyone successfully accomplished similar with iRule? Any help greatly appreciated.

Thanks.
