我有一个 ASP.Net 的MVC 4项目。如果我希望TinyMCE使用gzip，我需要在我的页面中使用以下内容(例如(：
<script type="text/javascript" src="/Scripts/tiny_mce/tiny_mce_gzip.js"></script>
<script type="text/javascript">
tinyMCE_GZ.init({
plugins: 'style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras',
themes: 'simple,advanced',
languages: 'en',
disk_cache: true,
debug: false
});
</script>
我注意到这在使用开发 Web 服务器的测试中效果很好，但是当部署到 IIS7 时则不然。进一步调查显示，针对以下请求显示 404(未找到文件(：
/Scripts/tiny_mce/tiny_mce_gzip.ashx?js=true&diskcache=true&core=true&suffix=&themes=simple%2Cadvanced&plugins=style%2Clayer...
ashx 文件确实存在于相应的文件夹中，但由于某种原因，IIS 不会提供它。我尝试添加以下路由处理程序，但都没有区别：
routes.IgnoreRoute("{resource}.ashx/{*pathInfo}");
routes.IgnoreRoute("{*allashx}", new { allashx = @".*.ashx(/.*)?" });
已解决
在搜索互联网后，我看到有很多人有同样的问题，似乎没有人找到解决方案！(即使在TinyMCE支持页面上(。所以我提出了一个解决方案，我希望它不会被:)
您唯一需要配置的是 Global.asax 中的"TinyMceScriptFolder"变量 - 它必须指向您的 TinyMCE 脚本文件夹 (duh((确保不要以/开头该路径，否则路由处理程序将拒绝它。在任何情况下，它都可以从您网站的根目录工作(
