Answer 1

Accept-Encoding is part of the HTTP Header, in addition to the parameters that you mistakenly sent as POST parameters:

Here is how to send it using HTTP Client:

httpPostRequest.setHeader("Content-Length", "6"); 
httpPostRequest.setHeader("Accept-Encoding", "identity"); 
httpPostRequest.setHeader("Host", "a.host.com");

Answer 2

If you want to change the Http Header Accept-Encoding, you chang like this

httpPostRequest.setHeader("Accept-Encoding", "identity");

Your codes

final List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
nameValuePairs.add(new BasicNameValuePair("Host: ", "a.host.com");
nameValuePairs.add(new BasicNameValuePair("Accept-Encoding: ", "identity"));
nameValuePairs.add(new BasicNameValuePair("Content-Length: ", "6"));

httpPostRequest.setEntity(new UrlEncodedFormEntity(nameValuePairs));

are used to send the value pairs in the http request body, NOT IN THE HEADER
