Django REST Framework: Accept Header With Many Large Quoted Parameters Burns ~19s Of CPU Per Request In Content Negotiat

Summary DRF's content negotiation parses each Accept token several times per request and never limits the number of tokens or their total size. Each parse ends up in Django's parseheaderparameters, which takes quadratic time when a quoted parameter value is packed with semicolons. On my machine a...
