VCL examples:
In the following examples only the stores with IDs "store_bug" and "store_huge" will be used.
The mse.set_weighting selects how stores should be weighted when a random store is needed for an object in the cache.

      sub vcl_backend_response {
                if (mse.set_stores("big")) {
                        set beresp.http.stores = "big";
                } else {
                        set beresp.http.stores = "unselected";
                }
                mse.set_weighting(size);
        }
