Hi Sabine,<div><br></div><div>If you include a period check, you automatically keep the session alive if the ‘check in’ interval is shorter than the session expiration duration.</div><div>If the session is dead, the callback cannot execute because it is no longer there, so you cannot write code that checks if the session is still alive from within you Seaside code on the server.</div><div><br></div><div>You can only do something on the client, if the Seaside session is reported to be ‘dead’ (i.e. when receiving an http response 403).</div><div>Using an error handler for the jquery ajax requests is the way we deal with those situations. It boils down to this:</div><div><br></div></span><div><div dir="ltr"><span class=""><div> script:</div><div> (html jQuery this load</div></span><span class=""><div> html: [ :r | … ];</div><div><span class="m_6549731349709680585Apple-tab-span" style="white-space:pre-wrap"> </span>onError: (html javascript alias: handleError))</div></span><span class=""><div> interval: 30 seconds);</div><div> with: [ html render: something].</div><div><br></div><div><br></div></span><span class=""><div>function handleError( event, jqxhr, settings, thrownError ) {</div><div><span class="m_6549731349709680585Apple-tab-span" style="white-space:pre-wrap"> </span>if(jqxhr.status == 403)</div><div><span class="m_6549731349709680585Apple-tab-span" style="white-space:pre-wrap"> </span>window.location = '/‘;</div><div>}</div><div><br></div><div>Instead of writing this for each ajax callback, you can also set a global ajax handler on the document when the page loads: <a href="http://api.jquery.com/category/ajax/global-ajax-event-handlers/" rel="nofollow" link="external" target="_blank">http://api.jquery.com/<wbr>category/ajax/global-ajax-<wbr>event-handlers/</a></div><div>You might also want to take a look at this chapter: <a href="http://book.seaside.st/book/in-action/session/recovering" rel="nofollow" link="external" target="_blank">http://book.seaside.<wbr>st/book/in-action/session/<wbr>recovering</a> if you want to respond in a specific way when sessions have expired</div><div><br></div><div>Does this help you?</div><div><br></div><div>cheers</div><div>Johan</div></span></div></div><div><br><div><blockquote style='border-left:2px solid #CCCCCC;padding:0 1em' style="border-left:2px solid #cccccc;padding:0 1em" type="cite"><div><div class="h5"><div>On 20 Apr 2017, at 18:04, Sabine Manaa <<a href="http:///user/SendEmail.jtp?type=node&node=4942970&i=0" rel="nofollow" link="external" target="_blank">[hidden email]</a>> wrote:</div><br class="m_6549731349709680585Apple-interchange-newline"></div></div><div><div><div class="h5"><div dir="ltr"><div>Hi,</div><div><br></div><div>is anyone having an idea for a solution of this problem: </div><div><br></div><div>I want that my seaside web app redirects the user to another page (login page) if the session is "dead*".
