Using Tempcode?
I'm going to split this post into two questions…When a user logs in, obviously a cookie is stored, am I correct? But what happens when cookies aren't enabled by the browser – what happens? Does Composr display a message requiring the user to enable cookies or does it somehow allow the user to still login? (I'm not very knowledgeable with cookies).
If Composr allows the user to still login, consider my next question…
I've got some Comcode pages that require input from the user when viewed, and depending on what is inputted by the user will dictate what else is displayed on the page.
For example: One page offers specific instructions to follow based on what U.S. state the user resides in. If the user didn't select a state in their profile, a popup appears on the page requesting them to input their state. Once inputted, the popup disappears and the page reloads – but this time it populates only information specific to the state they chose. This functionality utilizes the overlay system (which stores cookies), however, this system only works if the user has cookies enabled.
I need a way to check if the user has cookies enabled. If not, I'd like to display a message on the Comcode page explaining that the use of cookies are required to even continue.
HOWEVER, if cookies are required from the start (and assuming Composr warns the user if cookies aren't enabled), then my second question would be irrelevant as these Comcode pages are restricted to logged in users anyway, so I wouldn't need to check if cookies are enabled (in theory, they'd already be enabled if Composr requires them right?)

If Composr detects no cookies are present it will store the session ID in the URL, via the keep_session GET parameter.
Composr detects cookies by setting a cookie named 'has_cookies'.
This obviously doesn't work for the first page view.
So to detect cookies, just detect there are some cookies present already.

Not sure I understand that last bit, but that's okay.
Does Composr show any message asking the user to enable cookies?
I'm glad you informed me of the has_cookies cookie – I can check if this cookie exists using the Tempcode symbol I created, or check if keep_session is non-empty.
So consider this scenario:
User doesn't have cookies enabled but just logged in. User visits my Comcode page (which will check if has_cookies exists). Here I'll display an error that cookies are required. User then enables cookies in their browser.
Here lies a problem – I assume the user would have to log out and back in again in order for has_cookies to be created, yes? If so, I'd have to display an error message to logout and back in again. Do browsers normally require a reset (close and reopen) in order for cookies to enable?

Composr does not require cookies, so doesn't give an error message if they are not enabled.
has_cookies has nothing to do with logins. It is set on every page view.

So once the user enables cookies and refreshes the page, in theory, the has_cookies cookie should be automatically created, right?
