problem with session on IE

Posted on 2011-02-26

i am facing a bizzare problem:
i have a login mechanism that works great on Firefox,Safari and Chrome. the session array is populated as expected and i am able to login according to a role.

on IE the session array is empty, so the login mechanism just does not work.

it does not make any sense to me but maybe this is the issue:
i am moving my small mvc to html 5 so the only thing that has changed is the views.

now, on the version that still use the html 4 the session array work the same on all browsers even IE.

i am implementing boilerplate for html 5.

not sure if this info is relevant but that is the only change that was made so i gave it.

any idea?

best regards

Only IE9 supports HTML5 previous versions do not. FF 3 has partial support and IIRC Opera supports it 100%

i know but as i mentioned i use boilerplate, and so html render good on all browsers. the issue is the session on IE when its html 5.

does IE does not support sessions when using html 5? that sounds crazy. its a server content.

Good point - I got sidetracked by the HTML5 part.

Although the session is server content, it is usual for the session ID to be stored in a cookie on the client pc. Could the HTML5 element be interefering with cookies in any way?

I've done a bit of Googling and there seems to be a lot of questions out there about HTML5 and cookie problems, but there does not seem to be anything definite, no large luminous arrow flashing on and off and saying "Here is the problem" or even "there IS a problem".

OK - here are some suggestions:

1) Check the server date. IE is sensitive to the date being served up and if the server date is wrong it could be expiring the cookie with the session in it.

2) Make sure the domain name has only W3C characters - no underscores and such. Most browsers aren't bothered but IE has

3) If a FRAME or IFRAME is in use the problem could be related to something in the other pages or you may need to create a P3P header for IE
