Zend clearIdentity() and IE7 and Chrome Caching Problems

April 7, 2009 at 6:57 pm 3 comments

A few weeks ago I posted a blog entry about problems with Zend clearIdentity() with IE7 and Chrome but I’ve since found that the Zend Framework was not at the root of the problem.  After discussing the problem with a colleague we found that there was a line in the bootstrap.php file like:-


ini_set('session.cache_limiter', 'private');

This seems to be what was causing all our clearIdentity() issues.  This seems to give over caching control to the browser hence the reason why Firefox worked fine, IE7 intermittantly worked and Chrome couldn’t care less.  We changed this to:-


ini_set('session.cache_limiter', 'none');

and straight away all our clearIdentity() problems in IE7 and Google Chrome disappeared and everything started working as we would expect.

    continued due to fat fingers – componant that makes my ENTIRE MENU WORK – but nooooo its a child within a child – does the new shiny IE7 know what to do with this piece of common programming? Yes – it shuts down the page and hits the back button for you. Excellent.

    Are they fixing it? No – the work around for developers can be found on the microsoft site.

    Oh – or you could download IE8 – which it has been announced will only display web pages in Greek, the developer work around will be found on the MS site.

    sorry – been dealing with issues like this since yesterday and had to rant.
