| /** |
| * Basic implementation of OSGi HTTP service 1.1. |
| * |
| * TODO: |
| * |
| * - fuller suite of testing and compatibility tests |
| * |
| * - only exposed params are those defined in the OSGi spec. Jetty is |
| * very tunable via params, some of which it may be useful to expose |
| * |
| * - no cacheing is performed on delivered resources. Although not part |
| * of the OSGi spec, it also isn't precluded and would enhance |
| * performance in a high usage environment. Jetty's ResourceHandler |
| * class could be a model for this. |
| * |
| * - scanning the Jetty ResourceHandler class it's clear that there are |
| * many other sophisticated areas to do with resource handling such |
| * as checking date and range fields in the http headers. It's not clear |
| * whether any of these play a part in the OSGi service - the spec |
| * just describes "returning the contents of the URL to the client" which |
| * doesn't state what other HTTP handling might be compliant or desirable |
