    "Scope=Body",
    LAST);

			
web_url("generate_json_simple.asp",
    "URL=http://my_server/cgi-bin/json/generate_json_simple.asp",
    "TargetFrame=",
    "Resource=0",
    "RecContentType=text/html",

lr_log_message(">>> CorrelationParameter = %s", lr_eval_string("{CorrelationParameter}"));

The output is:

>>> CorrelationParameter = <array name="batter"><object><pair type="str" name="id">1001</pair><pair type="str" name="type">Regular</pair></object><object><pair type="str" name="id">1002</pair><pair type="str" name="type">Chocolate</pair></object><object><pair type="str" name="id">1003</pair><pair type="str" name="type">Blueberry</pair></object><object><pair type="str" name="id">1004</pair><pair type="str" name="type">Devil's Food</pair></object></array>
