Hubert,

Here is a simple unit test to run against a running server.

    @Test
    public void testDoubleContentLengthHeaders() throws Exception {
        HttpClient httpClient = new HttpClient();
        PutMethod putMethod = new PutMethod("http://localhost:9090");
        putMethod.addRequestHeader("Content-Length", "0");
        putMethod.addRequestHeader("content-length", "0");

        int rc = httpClient.executeMethod(putMethod);
        System.out.println(rc);

        assertFalse(400 == rc);
    }

I think the Grizzly code in question is somewhere around
com.sun.grizzly.util.http.MimeHeaders.java

    /**
     * Finds and returns a unique header field with the given name. If
no such
     * field exists, null is returned. If the specified header field is
not
     * unique then an {_at_link IllegalArgumentException} is thrown.
     */
    public MessageBytes getUniqueValue(String name) {
        MessageBytes result = null;
        for (int i = 0; i < count; i++) {
            if (headers[i].getName().equalsIgnoreCase(name)) {
                if (result == null) {
                    result = headers[i].getValue();
                } else {
                    throw new IllegalArgumentException();
                }
            }
        }
        return result;
    }


Which results in a 400 BAD_REQUEST response?

Does this make sense?

Regards,

Adrian

Hi Adrian,

Can you provide a sample to reproduce this issue.

Thanks,
Hubert
