I configured my Geoserver with GeoWebCache direct integration as described here.
It works fine and the WMS tiles are cached as expected.
Though for one of my Geoserver layers it is not working. The layer has a SQL view: SELECT * FROM gs_selectpoly_private(‘%ids%’)
The id is passed to the Server via the viewparams. Geoserver does not cache anything for these layers. Is it simply not possible to cache a WMS with a viewparameter or do does it require any special setting?
Any help is appreciated!

You need to use a Parameter Filter to let GWC know which values to allow for caching. Each combination of possible parameters (Gridset, Format, Style, etc) leads to another cache so this is something to be careful about.
The GWC documentation on Parameter Filters is here: http://geowebcache.org/docs/1.5.1/configuration/layers/parameterfilters.html
The Tile Caching tab for the layer in GeoServer includes an editor that lets you add and modify filters.
Thanks Kevin for the information! Very helpful.
I got it to work with the viewparams settings. But for some reason it only
caches tiles from Zoom 0 to 8. Everything beyond zoom level 8 is not
cached. Do you have an idea by what that could be caused?
