The solution includes the line

res.writeHead(200, {'content-type': 'text/plain'})

Neither the instructions nor the hints indicate the student should write this. Verification also doesn't test for this so it passes without.

Either:

1. the solution should not have this line; or
2. The instructions should make it necessary, the hints should mention writeHead, and verification should check the status code and headers

I err on the side of removing the line because this exercise isn't teaching HTTP.
