Bug 280011 – Add Quirks for overriding the Image Accept-Type for nhl.com

• Status: NEW
• Component: WebKit Misc.

[Karl Dubost]

Cloudinary worked with Apple to not send anymore JPEG2000 to websites. 
nhl.com seems to still be sending some JPEG2000 to Safari on iOS only.

We can create a quirk to force the server to not send the JPEG2000.


See Bug 269875 for booking.com in the past
https://github.com/WebKit/WebKit/pull/24923


Steps to reproduce:
1. On iPhone with Safari
2. Go to https://nhl.com/

Expected: 
See the images

Actual:
Some images are not visible.

is sent as JPEG2000 because this is the one requested with source selection

but if I look at understanding which of these are JPEG2000 vs JPEG, this is about half of them.

Note that a UA override is not solving anything.

I need to test Accept Headers. 

The Accept Header for 

# Safari

  Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Image: 
  Accept: image/webp,image/avif,image/jxl,image/heic,image/heic-sequence,video/*;q=0.8,image/png,image/svg+xml,image/*;q=0.8,*/*;q=0.5

I don’t know if something changed recently. 
But I can’t reproduce on macOs and iOS both iPhone and iPad.

It would be good to have other people to confirm. https://nhl.com/
