Answer 1

is this your code you use for the first and second request ?

if so, the problem is that you always create a new client, which results in new session on serverside, because the sessionid wich is stored in a cookie is not available.

so create your httpClient once, and use the same instance for both requests. should solve the problem

like this:

 DefaultHttpClient httpClient = new DefaultHttpClient();
            httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);

            HttpPost httpPost1 = new HttpPost(url1);

        httpPost1.setHeader("User-Agent", "Mozilla/5.0 (X11; U; Linux " +
                "i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)");
            httpPost1.setHeader("Accept", "text/html,application/xml," +
                "application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
            httpPost1.setHeader("Content-Type", "application/x-www-form-urlencoded");
        httpPost1.setEntity(new UrlEncodedFormEntity(params));

        HttpResponse httpResponse = httpClient.execute(httpPost1);
        HttpEntity httpEntity = httpResponse.getEntity();
        is1 = httpEntity.getContent();


        HttpPost httpPost2 = new HttpPost(url2);
        httpPost2.setHeader("User-Agent", "Mozilla/5.0 (X11; U; Linux " +
                "i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)");
            httpPost2.setHeader("Accept", "text/html,application/xml," +
                "application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
            httpPost2.setHeader("Content-Type", "application/x-www-form-urlencoded");
        httpPost2.setEntity(new UrlEncodedFormEntity(params));

        HttpResponse httpResponse2 = httpClient.execute(httpPost2);
        HttpEntity httpEntity2 = httpResponse2.getEntity();
        is2 = httpEntity2.getContent();
