boonex through proxy servers in some companies

Hello,

There seem to be some major issue with the Boonex site when used through a proxy server (e.g. in some companies). I have created a poll, copied the browser link and sent to a user by email. The user then has done the following:

1.)    Opened the email through/on his Gmail account and clicked on the link to the poll

2.)    It brought him to the screen where he could click on the ‘Join’ or ‘Log In’ buttons.

3.)    He clicked on the ‘Log In’ button and logged in; it then brought him to the Home dashboard (instead of the actual poll btw., where it should correctly have brought him).

4.)    He then went/clicked on the tab Polls, but it was asking him to log in again.

Then he tried to log in through a different proxy server (within the same company but through a different country), and probably because it was a fresh log in, it did allow him to log in to the site, then to the Poll and voted.

So the issue seems to be related to how the web site handles proxy servers in some companies, maybe something to do with some ‘Session information’ (http://en.wikipedia.org/wiki/Session ) ?

Whatever it is, could you please investigate and advise and/or fix it as soon as possible?

It maybe that caching policy is too aggressive on this proxy server.

To solve it in this particular situation you can try to add the following code to inc/header.inc.php file to tell proxy to not cache Dolphin pages:

header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");

It could help in this situation, but this is not recommended fix for other istes.
