Problems with html pages using httpForward

[xenaCode]

Hi James, I'm not sure if writing an issue is the right approach for asking this question. I have the next configuration:

mockServerClient("localhost", 8888).mockAnyResponse(
    {
        'httpRequest': {
            'method': 'GET',
        },
        "httpForward": {
            "host": "",
            "port": 8887,
            "scheme": "HTTP"
        },
        'times': {
            'unlimited': true
        }
    }
);

Then I run server: java -jar mockserver-netty-3.10.4-jar-with-dependencies.jar -serverPort 8888 and run SimpleHTTPServer on port 8887. It works good but when requested html pages, MockServer added Content-Type: text/plain, although in response its value is text/html. In Wireshark I got:

Src port: 8887
Status Code: 200
Response Phrase: OK
Content-Type: text/html 
etc.

Src port: 8888
Status Code: 200
Response Phrase: OK
Content-Type: text/html 
Content-Type: text/plain 
etc.

And it's displayed as plain text and not as html. It's obviously that MockServer added the second Content-Type to response. But why it's happend? I tried to change configuration in different way, but it's still not working.

Hope I am able to explain the scenario that I am struggling with. Any help would be really appreciated.

Thanks a lot, Xena

I faced exactly the same problem today, but in my case, it adds Content-Type: text/plain if it's not set, which changes the logic of processing in downstream application

I believe this should now be resolved, but as I couldn't manage to reduce the duplicate Content-Type header issue I can't be sure its 100% fixed. This fix will be in a new release in the next week or so.
