geoserver - How to join a WFS layer to a stand-alone table in OpenLayers

I'm a complete novice at OpenLayers, and am checking whether the following is possible.

I envisage a dataset of polygons in GeoServer, being served as a WFS layer into OpenLayers. The polygons won't have any attributes other than a unique identifier (eg State name).

The attributes for the polygons will be provided by a stand-alone table, which should match to the polygons via the unique identifier.

The join needs to be configured within the user's browser (rather than on the server) since the table will be unique to that user and that session - the table is generated dynamically as the result of the user's actions.

So my questions are:

• is it possible to join a WFS layer to a stand-alone table?


• is there any sample code showing how to set this up?

Thanks
