I am having trouble with proxy\_pass and PUT without a Content-Length  
header  
returning a 411 error.

# curl -XPUT [http://localhost:8080/](http://localhost:8080/)
411 Length Required
# 411 Length Required

* * *
nginx/1.1.19 # touch temp # curl -X PUT http://localhost:8080/ -T temp {"response": "ok"} #

Relevant configuration:

# Proxy to Backend Server

server {  
listen localhost:8080;

location / {  
proxy\_set\_header Host $http\_host;  
proxy\_set\_header X-Forwarded-Host $http\_host;  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
proxy\_pass http://backend\_server;  
}  
}

I found this post which seems to be the same problem:

Is there a way to get nginx to proxy PUT requests WITHOUT a  
Content-Length  
header?  
Does a newer version of nginx NOT suffer from this limitation?

Thanks,

PUT requests without a Content-Length header (either using chunked  
transfer encoding, or without a request body at all) are allowed  
in nginx 1.3.9+.
