允许从servlet下载Progressive？ [英] Allow Progressive Download from a servlet?

问题描述

我遇到了提供多媒体数据的servlet的问题。我正试图在iPhone上的移动safari中使用它，我得到服务器未正确配置错误。我使用Mac（Apache）上的网络共享服务相同的多媒体文件，它工作正常。我开始查看HTTP heades，看看servlet是否搞乱了一个标题。我注意到Apache设置了ETag以及Accept-Range。然后我谷歌周围，了解到iPhone可以使用渐进式下载。简而言之，我认为我需要在我的servleet中启用渐进式下载，我认为ETag和Accept-Range标头是其中的一部分。我之前从未这样做过，所以我想我会问这里有没有人能指出我正确的方向。我是否需要在servlet中实现完整的渐进式下载内容？我应该使用过滤器吗？我应该从哪里开始？

I'm having an issue with a servlet that delivers multimedia data. I'm trying to use it from mobile safari on the iPhone and I get the "server not configured correctly" error. I server the same multi-media file using a web share on my Mac (Apache) and it works fine. I start looking at HTTP heades to see if the servlet is messing up a header. I notice that Apache sets an ETag as well as an Accept-Range. Then I Google around and learn that the iPhone works with progressive downloads. Long story short, I think I need to enable progressive downloads in my servleet and I think the ETag and Accept-Range headers are part of it. I've never done this before so I figured I'd ask here if anyone could point me in the right direction. Do I need to implement the entire progressive download stuff in my servlet? Should I use a Filter? Where should I start?

推荐答案

看看这个文章。它创建了一个文件servlet，支持恢复下载，缓存和压缩内容。

Take a look at this article. It goes over creating a file servlet that supports resuming the download, caching and gzipping the content.
