Symptoms

On: 12.2.1.2.0 version, WebCenter Sites, Remote satellite servers (RSS) don't respond with 304 for "If-Modified-Since" headers

We've correctly configured "Last-Modified" headers for blobs based on Last-Modified=${updateddate} and they're working as expected. However, we've noticed that no matter what the "If-Modified-Since" header looks like, the RSS services always respond back w/ a 200 status code and the resource.

Using Browser Developer Tools, Network Trace when requesting a page, the following is shown:

Subsequent requests of same page returned HTTP 200, instead of 304 Not Modified
