Session-timeout implementation in openolat

[mamtay...@gmail.com]

Hi,

 

I have changed seesion-timeout tag's value from 60 to 5 in openolat\WebContent\WEB-INF\web.xml

<session-config>
    <session-timeout>60</session-timeout>
  </session-config>

 

but it is not reflecting the changes done , so please let me know what other changes need to be done in other files or in config file  to implement this.How session-timeout is handled in openolat.

Please revert asap.

 

 

Thanks,

Mamta.

Have a look at olat.properties:

# Session timeout configuration. 

# Note that this are default values only. If you want to change the configuration, open the administration panel 

# in OpenOLAT and change the values there. They are stored in olatdata/system/configuration/ and will override 

# the values from the olat.local.properties file.

# a) Session timeout in seconds for not-authenticated sessions (login screen etc). 

#    Keep small to prevent denial of service attacks. Default is 5 minutes.

session.timeout=300

# b) Session timeout in seconds for authenticated users and guest users. Default is two hours.

session.timeout.authenticated=7200

Regards

Thilo

Hi,

 

I have done changes but still not getting error message after whatever session time out was set.

In login.html following javascript block is written to display error messgae:

 

<
script type="text/javascript">
/* <![CDATA[ */
if
 ((window.self != window.parent) && window.parent.OPOL) {
// Page is loaded in an iframe within OpenOLAT because a session timeout occurred or
// system has been restartet in the meantime.
// Show error on main window
var title = "$r.escapeJavaScript($r.translate("timeout.title"))";
var message = "$r.escapeJavaScript($r.translate("timeout.message"))";
window.parent.o_afterserver();
window.parent.showMessageBox(
'error', title, message);
}
/* ]]> */
</
script>

 

Not able to understand what exactlty this condition is . On searching in worksapce OPOL , found in function.js

 

can you please let me know what 's this condition exactly?

 

Thanks

Mamta.

Hi Mamta

Normally content is loaded in a hidden iFrame and then replaced in the GUI using DOM replacement. We call this the AJAX-mode. 

When for whatever reason a redirect to the login screen happens (session timeout, server restart etc), the code in the iframe is the entire loginscreen and not a JSON resonse that is evaluated by the main window. This javascript code detects this situation and displays the error message in the visible main window. 

Cheers

Florian
