How to set single-cookie-header with the 4.3 API?

[d_k]

Hello,

I'm porting httpclient 3 code to the 4.3 API and I was unable to find a way
to set the single-cookie-header setting using the 4.3 API

The original line states:
params.setBooleanParameter(HttpMethodParams.SINGLE_COOKIE_HEADER, true);

And I was wondering how to write it with the 4.3 API.

If it helps I think the 4.1.1 API is something like this:

params.setBooleanParameter(CookieSpecPNames.SINGLE_COOKIE_HEADER, true);
