Re: IWS Rest Post, Response Code, and Best Practices on Error

HI Stephen

I followed The Nadir's  link for normal web services deployment
https://developer.ibm.com/tutorials/i-rest-web-services-server3/

So if you set the http header like

 if (%ERROR);
   httpStatus = H_SERVERERROR;
   return;
 endif;

It should work perfectly fine. I got it working for all of the below status
codes.

D H_OK            c                   const(200)
D H_CREATED       c                   const(201)
D H_NOCONTENT     c                   const(204)
D H_BADREQUEST    c                   const(400)
D H_NOTFOUND      c                   const(404)
D H_CONFLICT      c                   const(409)
D H_GONE          c                   const(410)
D H_SERVERERROR   c                   const(500)

This is my suggestion as It worked for me :)

Thanks
Anshul
