fckeditor是一个非常好用的网页在线编辑器，但是其配置往往会出现一些问题，比如在上传时提示“this connector is disabled Please check the"editor/filemanager/connectors/aspx/config.aspx”。很多人会手足无措，因为找不到config.aspx文件，只有一个config.ascx文件。

在config.ascx文件中有一个方法如下：

/**
  * This function must check the user session to be sure that he/she is
  * authorized to upload and access files in the File Browser.
  */
 private bool CheckAuthentication()
 {
  // WARNING : DO NOT simply return "true". By doing so, you are allowing
  // "anyone" to upload and list the files in your server. You must implement
  // some kind of session validation here. Even something very simple as...
  //
  //  return ( Session[ "IsAuthorized" ] != null && (bool)Session[ "IsAuthorized" ] == true );
  //
  // ... where Session[ "IsAuthorized" ] is set to "true" as soon as the
  // user logs in your system.  return false;
 }

细心的朋友会详细的读一下该部分的英文注释：不要简单的将返回结果改为true，因为这个方法是检查用户身份的，如果简单的改为true，则上传文件将不受任何限制。
