.htaccess文件重定向，如果不存在，远程文件上传 [英] .htaccess file redirect if not exists, remote file upload

问题描述

服务器A - 应用程序

Server A - application

服务器B - 从上传静态的媒体，没有应用

Server B - static media from uploads, no app

应用程序服务器A处理上传，验证和岗位作业来转换，转换后它通过复制（安装驱动器）移动到服务器B。然后该媒体文件经由服务器A上一个玩家在网页加载

App on Server A processes the upload, validates and posts a job to convert it, after the conversion it's moved to Server B via copy (mounted drive) . Then the media file is loaded via a player on the page on Server A.

我想通过远程URL HTTP来加载文件：//serverB/files/file1234.wtf 如果文件仍然是现在还没有（尚未复制），透明地重定向到的http：// serverA的/ tmp_files / file1234.wtf

I want to load the file via the remote url http://serverB/files/file1234.wtf and if the file is still not there yet (not yet copied), to transparently redirect it to http://serverA/tmp_files/file1234.wtf

如何使用htaccess的或任何其他的方式做到这一点？

How to do it with htaccess or any other way?

推荐答案

假设的Apache + mod_rewrite的，这应该工作在你的的.htaccess 上SERVERB：

Assuming Apache + mod_rewrite, this should work in your .htaccess on serverB:

RewriteEngine on

RewriteCond %{DOCUMENT_ROOT}/files/%{SCRIPT_FILENAME} !-f
RewriteRule ^/files/(.*)$ http://serverA/tmp_files/$1 [L,R=temporary]
