 In my application I use a frontend component FilePond
 (https://pqina.nl/filepond/) to perform photo file uploads.
 FilePond uses its own server protocol to manage temp files on the backend
 and sends a photo ID as a payload for DELETE request. According to
 RFC7231: "payload within a DELETE request message has no defined
 semantics", but it isn't forbidden. Django development server can't
 process a request that follows DELETE with payload as it regards the
 payload to be a part of the next request's first line.
 For example when photo ID is '0', next request is logged like this:
 {{{
 "0POST /accounts/profile/photo/ HTTP/1.1" 405 0
 }}}
 Quick and dirty fix for my View subclass is:
 {{{
 def delete(self, request):
 # Drain the incoming buffer
 request._stream.read()
 ...
 return HttpResponse(status=204)
 }}}
 When incoming data are wholly consumed by DELETE handler, subsequent
 requests work as expected.

 Best regards,
 Dmytro Yurchenko

Comment (by Simon Charette):

 Are you using Django 2.1.4 by any chance? If that's the case then it's
 possible you are affected by #30015 which will be fixed in 2.1.5 by
 b514dc14f4e1c364341f5931b354e83ef15ee12d.

Comment:

 In any case, I think we need a test or some some sample code reproduce the
 issue.

Comment:

 Hello! It is Django 2.1.4. I have checked it with `master` branch and the
 bug is no longer reproducible. I assume #30015 is indeed a more general
 description (and fix) of the same issue. Thank you!
