Bootstrap TokenInput取消之前的所有请求

Question

有人可以告诉我如何在输入令牌时取消以前的ajax请求吗？我遇到了多个ajax请求的问题，我的服务器因此而挂起。

            $('#Searchinput').tokenInput(getMyRestServer, {
            theme: "facebook",
            queryParam : "param",
            preventDuplicates: true,
            tokenDelimiter: "|",
            minChars: 5,
            hintText: "Type your search criteria here",
            noResultsText: "No Results found. Please refine your search...",
            searchingText: "Fetching results ...please wait...",
            allowCustomEntry: true});
