Caching of protected static content with Expires header: Expires Thu, 01 Jan 1970 03:00:00 EET?

[Violeta Georgieva <vi...@apache.org>]

Hi,

If the static content is not protected then by default it is cached and the
corresponding headers are set - see screenshot1 & screenshot2.
but when I put it as protected content the following headers are set:
Cache-control:private and Expires header: Expires Thu, 01 Jan 1970 03:00:00
EET - see screenshot3 & screenshot4
My question is why the expires header is set with this value? Doesn't this
prevent caching?

I'm running Tomcat 7.0.23

Thanks in advance
Regards
Violeta

I take it you are using Tomcat's caching directives, so...

Show us the relevant portions of the configuration file.
