Uploading: `curl: (52) Empty reply from server` after HTTP/1.1 100 Continue

[akuckartz]

When I upload gemet.rdf I see this:

$ curl -f --user admin:admin  -i -X PUT -H "Content-Type: application/rdf+xml" -T "gemet.rdf" http://localhost:8080/entityhub/site/gemet/entity
HTTP/1.1 100 Continue

curl: (52) Empty reply from server

I think there should be a HTTP/1.1 201 Created after the 100 Continue. Maybe a connection with #26 ?

In spite of this the upload seems to have been successfull:

$ curl -X POST -d "name=Politik&lang=de&limit=50" -H "Accept:text/turtle" http://localhost:8080/entityhub/site/gemet/find

Steps to reproduce:

$ curl -f --user admin:admin -i -X PUT -H "Content-Type: application/rdf+xml" -T "gemet.rdf" "http://localhost:8080/entityhub/site/gemet/entity"

(--user admin:admin)

And then to test if some entities were upoaded successfully:

$ curl -X POST -d "name=Politik&lang=de&limit=50" -H "Accept:text/turtle" http://localhost:8080/entityhub/site/gemet/find

[retog]

Did you happen to check if there is the same problem with a pristine stanbol version.

[akuckartz]

@retog I have not yet found time to do that. I will report here when that happened.
