Command
It may handle conditional requests, except that if it replies with a status of HTTP.NOT_MODIFIED, it must still reply with a content (the same content that it would have returned for an inconditional request). This is because further SSI commands down the line may decide thay they have been modified, and then a content must be emitted by SSIFrame.
