ErrorDocument -不设置缓存

Question

当apache为404提供服务时，我有一个重定向：

ErrorDocument 404 https://my404.com/image.jpg

# other rewrite rules that cannot be affected

如何仅在应用上述重定向时设置no-cache标头？

根据这个答案，How to prevent http file caching in Apache httpd (MAMP)将以下代码放在.htaccess文件中：

 <filesMatch "image\.jpg$">
 FileETag None
 <ifModule mod_headers.c>
 Header unset ETag
 Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
 Header set Pragma "no-cache"
 Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
 </ifModule>
</filesMatch>
