Hi Swaraj, 

Can I know where do I access this controller from? or where do I edit the controller? Where can i locate it?

By default when someone logins to odoo this controller redirect to backend menus to change that you have to inherit this corresponding route and change "self._login_redirect(uid, redirect=redirect)" to "your_url"

@http.route('/web/login', type='http', auth="none")
def web_login(self, redirect=None, **kw):

	​....rest of code 
	​if request.httprequest.method == 'POST':
    try:
        uid = request.session.authenticate(request.db, request.params['login'], request.params['password'])
        request.params['login_success'] = True
        return request.redirect(self._login_redirect(uid, redirect=redirect))
