What worries me is a scenario in which parts of the HTTP request are somehow malicious. I.e. as is the case for XSS, if responseString is set to contain some user-supplied JavaScript, it may lead to problems if printed back to the browser verbatim.
that's why
resp.setContentType("message/http");
Standard-conforming browsers will not interpret JavaScript (or other active
content) inside "message/http" bodies.
Of course, certain broken browsers ignore the ContentType header and
instead try to guess what the content type "really" is. That's a browser
bug, though, and even if it was exploitable you couldn't blame it on
the server.
