Re: GWT RPC offline caching

Hello Alex,

Sure you can do that. Have a look at [1], there's a post about how to
do the very same thing with using the HTTP GET cache - so this will
work also with non-html5 speaking browsers. Still that solution faces
the same problem of how to serialize and deserialize the data.
