Does the application require using the Expect header? If not, you should be able to configure a standard HTTP(S) monitor with the send string set to the full HTTP request headers and body.

 

 

If the app requires using the Expect header, I think you'll need to use an external monitor. I don't think there is a way to handle an Expect header in a standard HTTP monitor, wait for the HTTP 100 continue, send the request payload and then check the response. I think curl (Click here) supports sending the Expect header in HTTP 1.1. Once you get a curl request set up you could reference the curl command in an external monitor as describe in the Codeshare (Click here).
