[Flash Development Notes] How to Prevent Flash SWF files from being cached on the client

Problem
How can I prevent Flash SWF from being cached on the client? That is, how to make the SWF file appear in the Temporary Folder of IE browser?

Method:
Generally, we disable caching for dynamic pages (such as ASP and PHP) by setting the HTTP header in the language, but SWF cannot directly set the HTTP header. You can add an HTTP header in IIS from the server side:

Cache-control: "No-Cache"
Pragma: "No-Cache"
Expires: "-1"

The operation method is shown in the figure below:

However, when setting IIS, note that if an HTTP header is set for the entire website, the content of the entire site (such as JPG, GIF, CSS, and HTML) will not be cached, this will cause these files to be re-downloaded every time. You can createVirtual directoryAnd then set the HTTP header for this virtual directory to put the SWF file that is not cached in it.
