Hi Alexander,
The cache is implemented as MVC (or other web framework) level to take advantage of the fact that web servers provide caching in the HTTP context.
So Spark Core doesn't do that currently unless you go the precompiled route. I have worked on projects where we built mechanisms to watch for files changes, and constantly recompile on the fly and put into a local cache where something like and email service or other stand alone apps could reach them, but that is not part of core Spark. I've also gone the T4 Templates route in Visual Studio and invoked the Spark view engine core from tt files to constantly render the .cs files out as part of a Singe File Generator, but of course that only works from inside VS.
Hope those ideas help out.
Regards,
Rob
