35051	HEAD Responses Drop Headers	Paul Bailey	Paul Bailey	"When using runserver headers are dropped for head requests, in particular content-length. Because my HEAD request is serving a large body content, I do not include it in the body since it is just dropped.

Headers from runserver:
{{{#!python
Headers({'date': 'Tue, 19 Dec 2023 12:52:23 GMT', 'server': 'WSGIServer/0.2 CPython/3.11.2', 'accept-ranges': 'bytes', 'content-type': 
'text/html; charset=utf-8', 'x-frame-options': 'DENY', 'x-content-type-options': 'nosniff', 'referrer-policy': 'same-origin', 'cross-or
igin-opener-policy': 'same-origin'})
}}}

Headers from uvicorn asgi server:
{{{#!python
Headers({'date': 'Tue, 19 Dec 2023 12:54:49 GMT', 'server': 'uvicorn', 'accept-ranges': 'bytes', 'content-length': '121283919', 'content-type': 'text/html; charset=utf-8', 'x-frame-options': 'DENY', 'x-content-type-options': 'nosniff', 'referrer-policy': 'same-origin', 'cross-origin-opener-policy': 'same-origin'})
}}}

Notice the uvicorn properly includes the content-length header that was set in the view.
