DefaultHttpClient sub-class which includes a RequestAcceptEncoding for the request and response. Deprecation note: due to the way this class modifies a response body without changing the response headers to reflect the entity changes, it cannot be used as the "backend" for a caching org.apache.http.client.HttpClient and still have uncompressed responses be cached. Users are encouraged to use the DecompressingHttpClient instead of this class, which can be wired in either before or after caching, depending on whether you want to cache responses in compressed or uncompressed form.
