PUTs without "Content-Length" header line are rejected with a 411

[John Griffin]

Hey

I am using nginx to proxy couchdb. Performing the following returns a 411
Length Required:

curl -X PUT https://testing.com/abc --insecure --user john

Whereas passing a length of 0 in works fine:

curl -X PUT https://testing.com/abc --insecure --header Content-Length:0
--user john

Logging also shows it was rejected:

2010/04/03 14:41:20 [info] 22970#0: *1 client sent PUT method without
"Content-Length" header while reading client request headers, client:
10.211.55.2, server: testing.com, request: "PUT /abc HTTP/1.1", host: "
testing.com"

It seems that this was fixed for POSTs in 0.7.25 but not for PUTs. Shouldn't
PUTs be allowed without a Content-Length set?

My config is below including an attempt to use proxy_set_header to set the
content-length. Unfortunately nginx rejects the request before it gets
there.

Thanks
