requestHeadersNeverPass constant
Headers in the request which are never passed through to the target.
Important: these must be in all lowercase, otherwise matching won't work.

static const List<String> requestHeadersNeverPass = [
'host', // host will be recreated for the request
'connection', // HTTP/1.1 keep-alive is not supported
'keep-alive',
'te',

'proxy-authorization',
