Asp. NET to expand the capacity of the FileUpload upload file

Asp. NET extension fileupload can only upload small files, size within 4MB. If you upload a larger picture class, you can expand the size in the Web. config, the code is as follows

<system.web> <!--profile upload size, this configuration is the total size of the uploaded file does not exceed 15mb==15360kb, the cache threshold is changed to 100kB, so you can upload a slightly larger picture-    < HttpRuntime maxrequestlength="15360" requestlengthdiskthreshold="100  "/></system.web>

If it is a very large file, it is recommended to change the use of the control, if you crossing have anything to correct also please advise, if there is a better way also please tell in the next, thank you.
