SESSION_CONTEXT('LOCALE')/SESSION_CONTEXT('LOCALE_SAP')/$.request.language is empty on serverside

[DerGuteWolf]

Please add

  if(proxyreq.headers['accept-language'] != undefined) {
    headers['Accept-Language'] = proxyreq.headers['accept-language'];
  }

to server-basic-auth.js

Please give it a try.

I already tested this on my installation before opening the issue ;-), so, yes, this works.
What would be nice, but does not seem to be necessary is

        if(res.headers['content-language'] != undefined) { 
          proxyres.setHeader("content-language",  res.headers['content-language']);
        }

before

        proxyres.statusCode = res.statusCode;

What might also be better for performace, is preserving the "Accept-Encoding" header, but there seems further problems with this, I think at first the response header "content-encoding" is not preserved, thus giving illegible results (HANA sends gzip). But also the SAML form detection does not seem to work reliable when preserving this header.

Can you please fork, make the adjustments and then I merge the changes.
