This class is a near replica of the StaticHttpHandler. The only difference is that it does not cache resources. Caching (at least in how it was implemented by Grizzly) caused problems in Dog House as mime-types for all resources were being returned as "text/html" even if they were clearly css/png/etc.
Will drop this class when problem with StaticHttpHandler is resolved.
As of 2.2.18 the issue described above seems resolved, but now an error exists where certain resources throw a PendingWriteQueueLimitExceededException. Modified this class to support that fix. According to the issue tracker for grizzly it seems that the issue is fixed, but it doesn't seem to work :/
