{
   Response.Write("Key: " + arr1[loop1] + "<br>");
   String[] arr2=coll.GetValues(arr1[loop1]);
   for (loop2 = 0; loop2 < arr2.Length; loop2++) {
      Response.Write("Value " + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>");
   }

int loop1, loop2;
NameValueCollection coll;

// Load ServerVariable collection into NameValueCollection object.
coll = get_Request().get_ServerVariables();
// Get names of all keys into a string array. 
String arr1[] = coll.get_AllKeys();
for (loop1 = 0; loop1 < arr1.length; loop1++) {
    get_Response().Write(("Key: " + arr1[loop1] + "<br>"));
    String arr2[] = coll.GetValues(arr1[loop1]);

            + get_Server().HtmlEncode(arr2[loop2]) + "<br>"));
    }
}

var arr1, arr2 : String[]
