说明：  手机断点续传源码。手机上的应用越花哨就必然对应着需要下载的数据文件就会越大。目前绝大多数的手机浏览器，都支持gprs下载功能，所不同的是，绝大多数都没有断点续传的功能。里面提供的代码实现了断点续传的效果，运行nettest.exe，就会在其当前目录生成一个叫test.mp3的文件，屏幕上还显示下载进度。可以随时关闭，然后再次打开，看看断点续传的效果。在此基础上运用者可以根据自己所开发的实际需要更改代码，完成开发。
(Mobile HTTP source. Application of the more fancy phones necessarily correspond with the need to download the data files will be. At present, most of the phone' s browser, download gprs support, the difference is, most do not have HTTP features. Which provides the code to achieve the effect of HTTP, running nettest.exe, will be in its current directory to generate a file called test.mp3 screen also shows the download progress. Any time off, then on again to see the effect of HTTP. On this basis, can use developed according to their actual need to change the code, complete the development.)
