what happens if user block cookie?

Walle

What happen if user block cookies in browser and if some page trying to set cookies? Code will still try to set cookies anyway?

dagon

try, and fail, you should take that in to consideration when writing the site.

The server will always send the cookie if your PHP page sets one. If the browser blocks it, then it will not be stored by the browser on the client, so for all practical purpose it will be as if it were not sent (or as if it had expired immediately).

Sounds god, then it shouldn’t be any problem I hope with code I want run.

I want try this just to see what happens, if there will be some error etc, but don’t know how to block cookie on localhost? I know how to block in IE and FF with online sites but on localhost I don’t know. Can it be done somehow for test?

NogDog

The FireFox "Web Developer" add-on as an option for disabling all cookies.

you do it with the browser regardless of host, in ff

Tested with IE with block all "first-party cookies" but didn’t work. FF work block with and no error what I can see. That’s god. I will test litle more to see if there is some error anyway.

Thanks guys for your help.

you could try on IE to set both cookie types to 'prompt' that may give you more of a clue to what is happening, and make suer you delete the site cookie first, if it already exist maybe IE will allow it anyway.

I have "promt" as default on IE for first-party and "block" for third-party. Made some test again but it seems not work block from localhost with IE. FF work and can run some test with it instead.

Not sure on english but isn’t "party" like, you know, drink and stuff?

Normally 🙂

But this talk of 1st and 3rd party relates to the individuals (actual people, companies etc) involved. The site you visit being the first party, you yourself being the second party and any other site being a third party.
So if the site you visit sets a cookie for their own domain, that's a first party cookie. If they set the cookie for any other domain, that's a third party cookie.

Both IE and FF allows you to specify an exception list to default cookie handling. You specify a domain in combination with block or allow. Then, regardless of other settings, cookies from that domain will always be blocked or always allowed.
