I am trying to create a strophe connection with XMPP using javascript with my ejabberd server , i am able to make a connection when the page loads and able to disconnect when the disconnect button is clicked.

now the problem is , the connection is alive and if a user accidently refresh the page , then my javascript is trying to make the connect again , and in response to that i am getting. (its just because the previous connection might be still alive )

<body xmlns='http://jabber.org/protocol/httpbind'>
    <failure xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
            <not-authorized/>
    </failure>
</body>

and after a while if i refresh the page again then connection will get established successfully, so how can i reset the connection in case if the page is accidently refreshed so that a user get a seamless connection.

What authentication mechanism(s) or backend are you using? – Zash
Authentication is implemented in ejabberd so it is DIGEST-MD5 PLAIN – Hunt

If you want to have the connection survive across a page refresh, keep the jid, sid and rid variables, along with any other state you need, in something like sessionStorage. You can then use attach() to resume the XMPP session.

I guess you login with the same JID, which is not allowed. You need to set a random resource to your JID to ensure no collisions. So instead of logging the user with JID user@domain you should use the JID user@domain/some_random_resource.

Also as a matter of principle you can also listen to onbeforeunload and disconnect there. This will not work with webkit-based browsers but will work with the rest.
