[Geoserver-users] GWC Caching Issue

GeoServer GeoServer User
1

Hi together

I try to cache my data with Geowebcache. The only problem I have is, that I
try to set the cache expiry tag, but it doesn't work. I set it to 120 for
testing purposes. Am I right that it should now regenerate the tiles every
120 seconds?

This is the logsnippet when I reload the gwc configuration:

It should, but it's been a long time since I've tested it. Is this GeoServer 1.7.4 ?

I will definitely have a look, but it's unlikely that I will get to it before next week.

Hi Arne

Yes it is 1.7.4. Can you explain me what this snippet means? Because I'm
pretty sure that my xml ist ok with the standard.

01 Jun 14:14:10 INFO [util.XMLConfiguration] - cvc-complex-type.2.4.a:

Looks like you've got 1.1.0 elements in a file that says it's 1.0.1, and then that gets mangled a bit by XSL. In most cases XStream doesn't care, but I intend to use your configuration when I have time to test, to cover that aspect too.
