Re: HTTP PUT Request - StreamDevice

Hi Dirk,

I was able to get it working. Thank you for all of your suggestions. Adding additional header information ended up being the solution.

    out 'PUT /io/net/hostname/value.json HTTP/1.1\r\nHost: http://129.57.203.137/io/net/hostname/value.json\r\nContent-Type: application/json\r\nContent-Length: 16\r\n\r\n"injivcont1"';
    in '%*s';

Omitting content length would result in the hostname not being set.

Any recommendations on how can I dynamically calculate the Content-Length header value for variable-length payloads in StreamDevice for PUT requests?

Appreciate your help,

Kyle

If you are getting a response, you should add a matching 'in' command to your
protocol. And then you may not need to disconnect. Still use the http option in
drvAsynIPPortConfigure.
