Similar to the use of captcha images you can easely track and advise user who don't accept
cookies, especially no session cookies without redirecting them.
so here's the deal:
if the main script (which outputs the html) doesn't have a value in it's session which
says that a session is running successfully a different value is saved in the session and an image
is included in the html which checks wether the session-check value is set or not.
If it's set the image-script sets a confirming value which will verify the session to be
running correctly and output a transparent 1*1px gif.
If the value is not set the image outputs an advising image which tells to allow cookies.
You can also wrap the image with a link who refers the user to a page addressing the cookie issue.
If the 1px trans is generated the user will hardly find the link, but if the error-image is
generated he will surely be able to click it.
pros:
- works
- no rerouting, you can see the result on the first page opened by the user
- no javascript
cons:
- bad accessebility (if you give the image an alt-text any blind user will read it at least on the
first call, but you cold also write this into the alt text... so maybe there are no cons)
i hope this'll help
