Webkit apparently handles Content-Type: x, y different from Content-Type: x Content-Type: y Both examples are invalid, but the fact that the outcome differs hints at inconsistent code with respect to re-combining field values. Note that both Firefox and Chrome show consistent behavior here. 1682625 1 webkit-bug-importer 2020-08-25 05:17:18 -0700 <rdar://problem/67732394> 1992298 2 ahmad.saleem792 2023-11-13 15:20:49 -0800 Based on discussion on Slack with Alex, it is something to be fixed in CFNetwork. So marking this as "RESOLVED MOVED".
