Ability to add personal header

[Puliyo]

It will be great if there's an ability to add user defined header.

private String newResponseHeaders(GetRequest request) throws IOException, ProxyCacheException {
        String mime = source.getMime();
        boolean mimeKnown = !TextUtils.isEmpty(mime);
        int length = cache.isCompleted() ? cache.available() : source.length();
        boolean lengthKnown = length >= 0;
        long contentLength = request.partial ? length - request.rangeOffset : length;
        boolean addRange = lengthKnown && request.partial;
        return new StringBuilder()
                .append(request.partial ? "HTTP/1.1 206 PARTIAL CONTENT\n" : "HTTP/1.1 200 OK\n")
                .append("Accept-Ranges: bytes\n")
                .append(lengthKnown ? String.format("Content-Length: %d\n", contentLength) : "")
                .append(addRange ? String.format("Content-Range: bytes %d-%d/%d\n", request.rangeOffset, length - 1, length) : "")
                .append(mimeKnown ? String.format("Content-Type: %s\n", mime) : "")
                .append("\n") // headers end
                .toString();
    }

Something like this:

private String newResponseHeaders(GetRequest request, HashMap<String, String> headers) {
      StringBuilder _headers = new StringBuilder(newResponseHeaders(request));
      for (Map.Entry<String, String> entry : map.entrySet()) {
            _headers.append(String.format("%s: %s\n", entry.getKey(), entry.getValue()));
      }
      return _headers.toString();
}
