Hi,
I am trying to make multiple posts over a https channel (basically fill out
an interview process).The first post works fine and the desired response is
obtained from the server, however the second post is causing an internal
Error on the remote server, assuming that the post data and headers are set
correctly is there anything missing in the code (I have used this earlier on
a http connection and it worked fine, so I am wondering if some extra
configuration is required for Https connection)??
Code-------

*import* java.util.ArrayList;

postToRemoteServer.postData();
}
*public* *void* postData() {
String uri;

HttpPost postMethod = *null*;
String sessionCookie = *null*;
*try* {

initializeConnectionHeaders(postMethod);
// Execute the first post
String firstResponse = client.execute(postMethod,

logger.info(firstResponse);

UTF_8*));
httpost.setHeader("Referer",
"Referer url goes here");
initializeConnectionHeaders(httpost);
firstResponse = client.execute(httpost, responseHandler);
logger.info(firstResponse);
//This response indicates an error at the remote server
} *catch* (IOException e) {
logger.error("Post to remote server Failed caused by" +
e);
}
}
/**

*private* *void* initializeConnectionHeaders(HttpPost method) {
