Hi,
I think I have now worked out that the option needed is on the publishing tab
which has Caching Settings at the top of the page with a response cache headers
option. If I set the value in there then the response headers appear but I'm
still a little confused as to why we have a check box?
Surely we should just include the header if we have a value in the Cache Time
(seconds) box?
As stated below, it appears that the Expire client cache after n seconds on the
Tile Caching page is not effecting the response headers at all so it is a bit
of a mystery to me what it is meant to do?
I still have a bit of a problem as I'm really trying to set the option for a
layergroup and of course that doesn't have the Caching Setttings option on the
publishing tab. I have set the relevant options on the Tile Caching tab but as
far as I can see there is no way to alter the cache expiration response header
on a layergroup using the UI. Did I miss another option somewhere or does that
sound correct to you?
I might try to set the response cache headers option to true in the XML and see
if it works anyway.
Thanks,
Paul

Subject: Question about default tile expiration
Hi,
This is hopefully an easy question. On the tile settings tab for a layer there
are two options for tile expiration (server and client). In brackets it states
that setting these to 0 will default to the system default but where is the
setting for the default?
I looked under Caching Defaults in 2.12.0 but I can't see an option and adding
it to the GWC config file as <expireClients> results in an error as well.
I have tried setting the values for a particular layer to 600 but I still get a
header of Cache-Control: no-cache so we wanted to check what the default was
set to.
I'm sure I'm missing something obvious but I thought I would ask anyway; any
tips would be great?
Thanks,
Paul
