These two lines are not needed. The default status code is HttpStatus.OK. If no
reason phrase is specified there is a default mapping from status code to reason
phrase.

+              response.statusCode = HttpStatus.OK;
+              response.reasonPhrase = "OK";

Here you can just do

  f.openInputStream().pipe(response.outputStream);

instead of

  var content = f.readAsBytesSync();
  response.outputStream.write(content);
  response.outputStream.close();

pipe will close the output stream when done.

+              var content = f.readAsBytesSync();
+              response.outputStream.write(content);
+              response.outputStream.close();
+            } else {
+              response.statusCode = HttpStatus.NOT_FOUND;

[Søren Gjesse, 2012/09/21 07:08:09]

No need to set reason phrase.

+              response.reasonPhrase = "Not Found";
+              response.outputStream.close();
+            }
+          }
+        } catch(e,s) {
+          response.statusCode = HttpStatus.INTERNAL_SERVER_ERROR;
+          response.reasonPhrase = "$e";

Maybe add

response.writeString(s.toString());

+          response.outputStream.close();
+        }
