ie gets wonky on for/in loops , includes inherited properties , methods. try adjusting for/in loops add check object being iterated has each item own property:
for (k in val) { if (object.prototype.hasownproperty.call(val, k) && val[k] !== null) { tmp.push(_http_build_query_helper(key + "[" + k + "]", val[k], arg_separator)); } }
