When a message with an attachment on Discord is deleted and the attachment is not requested within 2 minutes after deletion, Discord removes the attachment from its CDN.
This PR sends an HTTP request to the CDN endpoints corresponding to the attachments when a message is deleting which tells Discord to preserve the attachments (at least for a few hours from what I have seen).
I don't think this behavior is documented so it might not work like this forever.
This may not work that well if this is a regional cache which does not seem the case since I am able to access these attachments with a VPN.
