User uploaded images are not cached in browser

Question

Hi,

we just introduced Confluence as our corporate intranet when I noticed that all images that where uploaded by users get an expires http header of January 1st, 1970. As a results they never get cached.

Is there a way to change this behaviour ?

Regards,

Michael

Sure! It's just a web server and Confluence is just a web app. If you're using it in production, you'd likely make other configuration changes anyway.

Do you really suggest to change the tomcat confluence was bundled with?

I doubt this is a Confluence setting. You can modify the headers in Tomcat:
