Today, the system worked! I received an email from a user asking if I could add support for custom status codes to Post Test Server and I was happy to oblige. So I have added a new parameter which can be passed in the URL called: status_code which causes the server to return a response with the header set to: HTTP/1.0 $status Custom Status (where $status is the value of status_code). Regardless of what code is requested the post will still be dumped in folder in the usual way.
To make it very clear, hitting this url:
http://posttestserver.com/post.php?dir=bot&status_code=650
will cause the server to respond with HTTP/1.0 650 Custom Status.

Henry curious if you had thought about letting us set status code specific information….I wanted to test some browsers using post and returning a status code of 307…when this is done I like to be able to provide the redirect location…. its called location, and should trigger an automatic redirect (maybe not automatic) but I wanted to confirm

I have a planned overhaul of this site. And in my next version I want to give users the ability to specify the entire response, headers and all. Because you are right, this isn’t possible today and it would be a neat feature.
