Content fetched through the FTS CDN (fts.rbxcdn.com) does not return the Last-Modified header as opposed to the secure CDN (scX.rbxcdn.com). This has been the expected behaviour for over a decade.
Reproduction steps:
- Request https://assetdelivery.roblox.com/v1/assetId/1818 until it returns a fts.rbxcdn.com CDN url
- Open the browser’s developer tools in the window and switch to the Network tab
- Send a request to the fts.rbxcdn.com CDN url
- Click on the row for the newly sent request and view it’s headers
Expected behavior
Expected: Last-Modified header is present like scX.rbxcdn.com urls
Actual: The Last-Modified header is not present
