Can anyone quickly give me info on how to set the "samesite" cookie. What I need to know is the exact format. Background: for a number of years we have been able to connect to our credit card acquirer with this cookie set in the first line of the PHP code. : setcookie("samesite","strict",0,"/","coaxpublications.ca",true); We don't actually use cookies for anything but this is, I think, needed to pick up the configuration headers. Only one I know of is this in the httpd.conf file: Header always set Strict-Transport-Security "max-age=63072000;includeSubDomains For the last two weeks we haven't been able to take any orders and after a lot of Googling I still don't know exactly what is wrong with this format. Firefox gives the following error: " Cookie “samesite” does not have a proper “SameSite” attribute value. Soon, cookies without the “SameSite” attribute or with an invalid value will be treated as “Lax”. This means that the cookie will no longer be sent in third-party contexts. If your application depends on this cookie being available in such contexts, please add the “SameSite=None“ attribute to it. To know more about the “SameSite“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite " Trouble is, to me the explanation is a clear as mud. Sorry folks, I know I'm asking on the wrong help list but I figure that most people here will know the answer immediately. Thanks in advance. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
