HTTP/0.9 problem

Hello,

We have a problem that CURL complains about HTTP 0.9, but it's not HTTP 0.9...

e.g.

  Trying x.x.x.x:3290...
TCP_NODELAY set
Connected to xxxx (x.x.x.x) port 3290 (#0)
POST /aprox-http/request HTTP/1.1
Host: xxxx:3290
Accept: */*
Content-Type: application/json
Content-Length: 1033
Expect: 100-continue

Mark bundle as not supporting multiuse
HTTP/1.1 100
Done waiting for 100-continue
formdata={"some JSON...."}We are completely uploaded and fine
HTTP/1.1 200
Accept-Ranges: none
Allow: TRACE, OPTIONS, POST, GET, HEAD
Connection: close
Content-Length: 441
Content-Type: text/html
Date: Tue, 26-Nov-2019 14:30:01 GMT
Server: Net::HTTPServer/1.1.1 AProx/1.0
Received HTTP/0.9 when not allowed

Closing connection 0

Has someone seen this before?

Sincerely
Christian
