I would like to specify "Connection: close" for a request that I load in WKWebView - which actually CAN be done by setting the value on the request that is loaded (and it actually works). However, the documentation at https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 states that it shouldn't be used because the URL loading system handles persistent connections for you.
So - my question is how can I indicate to the URL Loading System that I do NOT want to use persistent connections for this particular request? Or - am I safe to just set the header even though it's listed as reserved (because - as mentioned - it does work)?
