[Geoserver-users] GWC, Layer Groups, TIME dimension

Discussion:

I have several related layers, each with a TIME dimension, for which I
currently cache tiles with GWC with each TIME dimension having a separate
cache in GWC.

I want to combine those related layers in a Layer Group.

The Layer Group seems to respond appropriately to a TIME parameter in the
URL.

However, it seems there is no way to get GWC to cache the TIME dimension
separately for a layer group.

Is this correct?

Thanks,

Mike Grogan

I will follow-up by saying:

1. There is no option in the Geoserver GUI for this. The "Parameter
Filter" section is blank. The section shows up, but there is nothing
there.

2. If I manually edit the gwc-layers xml config (for this layer
gwc-layers/LayerGroupInfoImpl--c6eb92d_1412c1e1b5a_-2ef6.xml) and add in:

<parameterFilters>
<regexParameterFilter>
<key>TIME</key>
<defaultValue></defaultValue>
<regex>.*</regex>
</regexParameterFilter>
</parameterFilters>

then gwc does seem to respect the TIME parameter and creates a separate
cache for different TIME values.

Thanks,

Mike

I will have a look in 2.4. This is on 2.3.3 and haven't brought 2.4 into
production yet. For the time being, I just manually added the parameter in
the XML config for the gwc layer and it seems to be caching w/time
parameter appropriately.

You could add the parameter filter yourself by using the REST API, or
using the new parameter filter editor UI in GeoServer 2.4.
