Hello,
I've to submit post form with username,password and 2 hidden parameters.
It seems to be logged in, but then redirection fails:

public static void main(String[] args) throws Exception {
HttpClient client = new HttpClient();
client.getHostConfiguration().setHost(LOGON_SITE, LOGON_PORT, "http");
client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY); //

(initcookies.length == 0) { System.out.println("None"); }
else { for (int i = 0; i < initcookies.length; i++) {
System.out.println("- " + initcookies[i].toString()); } }
PostMethod authpost = new PostMethod("/"); // Prepare

password}); client.executeMethod(authpost);
System.out.println("Login form post: " + authpost.getStatusLine().toString());
// release any connection resources used by the method

only way of telling whether logon succeeded is // by finding a session

{ System.out.println("None"); } else { for
(int i = 0; i < logoncookies.length; i++) {
System.out.println("- " + logoncookies[i].toString()); }
} // Usually a successful form-based login results in a redicrect to
// another url int statuscode = authpost.getStatusCode(); if
((statuscode == HttpStatus.SC_MOVED_TEMPORARILY) || (statuscode ==
HttpStatus.SC_MOVED_PERMANENTLY) || (statuscode ==
HttpStatus.SC_SEE_OTHER) || (statuscode ==
HttpStatus.SC_TEMPORARY_REDIRECT)) {
//authpost.setFollowRedirects(true); Header header =
authpost.getResponseHeader("location"); if (header != null) {
String newuri = header.getValue(); if ((newuri == null)
|| (newuri.equals(""))) { newuri = "/"; }
System.out.println("Redirect target: " + newuri);
GetMethod redirect = new GetMethod(newuri);
redirect.setRequestHeader("Cookie",logoncookies.toString());
client.executeMethod(redirect); byte[] responseBody =
redirect.getResponseBody(); System.out.println("Redirect: " +
redirect.getStatusLine().toString());
System.out.println("Redirect: " + redirect.getRequestHeader("path"));
// release any connection resources used by the method
redirect.releaseConnection(); } else {
System.out.println("Invalid redirect"); System.exit(1);
} } }
I obtain code 302 for login page,
andauthpost.getResponseHeader("location")=/default.php (that's correct)but
redirection doesn't work and variable responseBody contains html code from
login page (index.php)Any idea, please?
