The reason I ask is sometimes Facebook when I am using it locks up and my fan goes crazy I close Safari and restart the browser and it works fine again. It acts like it is restarting a download over and over again.


Because it is. Those websites use "infinite scrolling" for delivery. Accept-Ranges tells the server that it does not have to re-deliver the entire JSON dataset for the scrolling part in full, every few seconds.

That header is defined by <https://www.rfc-editor.org/rfc/rfc9110#name-accept-ranges>

Hello fellow Squid community can you please help?

Should I be using the following if I have SSL certificates, dynamic updates, 
StoreID, and ClamAV running?

*request_header_access Accept-Ranges deny all reply_header_access Accept-Ranges deny all request_header_replace Accept-Ranges none reply_header_replace Accept-Ranges none*

None of the documents show what Accept-Ranges does

Can anyone help explain this to me?
