推荐答案
用户查看的任何文件都将加载到他们的计算机.其中包括所有图像，pdf文件，html等.
Any files that the user views are loaded to their computer. This included all images, pdf files, html whatever.
如果要防止下载pdf，则有基于Flash和Java的pdf查看器.它们向用户显示内容，但用户未获取pdf文件.
If you want to prevent downloading of the pdf, there are Flash and Java based pdf viewers. They show the content to the user, but user doesn't get the pdf file.
