.net GET NOTESSESSION question

HCL Domino Domino Forum
1

Hello folks,

I got a .Net APP which has a login form that will authenticate the user to a domino APP(names.nsf?Login…)

thats ok and easy.

The problem ( i think its a problem as im a .net newbie) is how could i check if the user´s session(notessession) is still alive?

if not logged, it will ask for login, if logged it will proceed the tasks

like

if(user.session) keepGoing()

else goToLogin()

how do i approach that in .Net ?

any doubts or tips feel free to post!

T.I.A,

fferrandini

Here is my article about logging in to Domino from PHP: IBM - United States make it work in .NET would be very similar.

You login to Domino using db.nsf?Login and POST username and password. As result of the request you get a session cookie. You save that cookie internally and then can append it to your request to some protected page on Domino server to see if you get a login response or the actual page. If you get a login page, then the session has expired and you must login the user again (using saved username and password?).

Here is the PHP code:

$req=“username=john+doe&password=john123”;

$opts = array(

“http”=>array(

"method"=>"POST",

"content" => $req,

"header"=>"Accept-language: en\r\n" . 

"User-Agent: Mozilla/4.0 (compatible; 

       MSIE 6.0; Windows NT 5.1)\r\n"

)

);

$context = stream_context_create($opts);

if (!($fp = fopen(“http://server.com/maildb.nsf?login”,

              "r", false, $context))) {

die(“Could not open login URL”);

}

$meta = stream_get_meta_data($fp);

for ($j = 0; isset($meta[“wrapper_data”][$j]); $j++)

{

if (strstr(strtolower($meta[“wrapper_data”][$j]), ‘set-cookie’))

{

$cookie = substr($meta[“wrapper_data”][$j],12);

break;

}

}

fclose($fp);

$_SESSION[“DominoCookie”]=$cookie; //save cookie for later use
