Cache control in production mode in 1970?
This date at least makes Safari not cache any javascript in production mode.

There is a related JIRA: https://issues.apache.org/jira/browse/TAP5-1119
I don't think they discuss the root of the problem, which looks like
org/apache/tapestry5/internal/services/assets/StackAssetRequestHandler.java, line 183.

Re: Cache control in production mode in 1970?
Posted by Lenny Primak <lp...@hope.nyc.ny.us>.
This looks like a bug.
tapestry5/internal/services/ResourceStreamerImpl.java, line 102
long lastModified = streamable.getLastModified();
looks like that returns zero (1970) and expired header is set later
to (+10 years) to 1979.
I think a null check should be made there or at least see why its returning null.
There maybe a deeper problem there.

I don't understand your point Steve. I would think the proper expiration header would be sometime in the future and not a null value? Seems like either a bug in tapestry or the app server to me.

Yep, no surprise there. That would be a Java limitation since JDK 1.0:
