[Xerte-dev] IE 10 and Xerte Session Cookies (workaround)

[Thomas Rochford]

Hi,

 

I've been having a lot of difficulty getting my internet website to work
correctly with XoT 2.0 when using IE 10, although it works fine with Chrome
and works fine when running the same version from 'localhost' using a MAXOS
stick (i.e. xampp on a USB stick). When running it from my web server I get
an error when I try to edit an LO saying 'Session ID not set'. I do not get
the same error when using Firefox or Chrome and obviously not with the MAXOS
version as this has no authentication and therefore does not try to set a
session cookie.

 

It seems that telling IE 10 to allow cookies from a particular site may not
be enough you also have to turn off 'protected' mode. An alternative method
is to add the site to your 'trusted' zones.

 

For those who prefer an illustration of the problem (and the solution)
please view the attached image which shows five sessions with the same
Learning Object. These are numbered 1-5 as below

 

1) (localhost) no problems (because no authentication and/or trusted?)

2) (tcrochford) error message because 'protected mode' enabled and site is
in 'internet'/'untrusted' zone)

3) Firefox - no problems

4) Chrome - no problems

5) (tcrochford) disabled protected mode - no problems. Would also have
worked if I made my site 'trusted'

 

I have documented this in case it causes problems in another context. I no
longer have easy access to an earlier version of IE although I recently saw
the problem on a University laptop at ARU when attempting to demo the new
version to a colleague. I can confirm however that the problem is the same
with W7; it's not specific to W8.

 

Maybe we should consider giving a different error message in future versions
(e.g. 'Unable to write Session Cookie - please adjust your browser settings
to allow this') if there is a problem writing the cookie and reserve the
current message for server-based errors.

 

Kindest Regards,

Thomas
