Infinispan L1 cache question.

Hello All,

We are contemplating using Infinispan and/or other solutions for our cache usage. Traditionally we had one single server and then a client (a java based swing client) and to make calculations (its financial software) easier we started using homegrown cache implementation.
One of the features we implemented is large caches on serverside and some near cache on the client side.
While I am looking at Infinispan as a potential replacement for our homegrown solution (which I think has outlived its life) the question is

Can I use L1 cache on the client side without it being part of the data grid? Assuming we remove all the server side caches and have a different datagrid server(s).
