Is it done for CURL only for POST when setting CURLOPT_POST?
Is it also happening for other methods like PUT?

What happens if there are elementSize but no provided HTTPHeaderName::ContentType?
If it is the default CURL, does it align with other ports?

libcurl only behaves like this on POST. I guess POST is more popular use case for libcurl.

That is covered by this case in the test:

    req.open("POST", "methods.cgi", false);
    req.send("");
    log('POST(""): ' + req.getResponseHeader("REQMETHOD") + "(" + req.getResponseHeader("REQLENGTH") + " bytes), Content-Type: " + req.getResponseHeader("REQTYPE"));

All three ports returns that content type is sent as "Content-Type: text/plain;charset=UTF-8".

I confirmed this difference. It is weird the result was different than at home. I'm double check my build env.
