- rapnie 5y agoYes indeed, to request the OpenGraph metadata. Though technically not needed I assume that any hyperlink will be readable by WA/FB. Anyone knows if these requests go via their own servers?
- StavrosK 5y agoI just checked the web UI by pasting a link and didn't see a request go out to the domain, so I assume it went through the websocket to FB.
