httpclient 4 POST 自動重新導向

由於需要用到httpclient 4 的自動重新導向功能，查看源碼找到在DefaultRedirectHandler裡是這樣處理的，

public boolean isRedirectRequested(
            final HttpResponse response,
            final HttpContext context) {
        if (response == null) {
            throw new IllegalArgumentException("HTTP response may not be null");
        }
       
        int statusCode = response.getStatusLine().getStatusCode();
        switch (statusCode) {
        case HttpStatus.SC_MOVED_TEMPORARILY:
        case HttpStatus.SC_MOVED_PERMANENTLY:
        case HttpStatus.SC_TEMPORARY_REDIRECT:
            HttpRequest request = (HttpRequest) context.getAttribute(
                    ExecutionContext.HTTP_REQUEST);
            String method = request.getRequestLine().getMethod();
            return method.equalsIgnoreCase(HttpGet.METHOD_NAME)
                || method.equalsIgnoreCase(HttpHead.METHOD_NAME);
        case HttpStatus.SC_SEE_OTHER:
            return true;
        default:
            return false;
        } //end of switch
    }

顯然POST方法不支援，只能手動處理了。
