我说的stream，就是把链接放入浏览器，就立即开始播放，一边播放，一边下载。
如果我用godaddy的服务器，放入一个静态文件，是可以这样的。
下面是我放入google app engine的servlet, 和一般servlet略为不同就是input/
outputstream有些不同，但原则都一样，结果是浏览器等待文件下载完毕后才打开，请
问为什么？如何改进？谢谢

scientists to determine hormones and antibiotics in a variety of complex
matrices, investigate the fate and transport of manure-associated steroid
hormones and veterinary antibiotics derived from dairy and beef farms,
develop/utilize models to demonstrate the transport processes of these
contaminants in the environment, and monitor the occurrence of steroid
hormones and veterinary antibiotics in water bodies surrounding dairy and
beef farms. He/she will be actively engaged in most aspects of the research
and will coordinate daily research activities, data management, and multi-
criteria systems analysis, in conjunction with the project management team.
Qualifications: Applicants must have a Ph.D. in chemistry, environmental
engineering, chemical engineering, soil, hydrology or related fields.
Experience with LC-MS analysis and column experiments and model simulation
is preferred.

我是否要加上 setHeader来设定这些？到底是什么使得原来的goDaddy上面的http://xxx.com/a.mp3可以立即播放，而我的通过servlet的要下载后？我把 res.setHeader("Content-Disposition", "attachment; filename="" + "a.mp3
删掉也不行。
