Don't set cookies until you need to (for cacheability) #30

Closed timkelty closed 6 months ago

It appears that regardless of configuration, if the plugin is installed, web requests will always end up with a an _ia cookie set. I thought this would be solely controlled with autoSendPageView, but that doesn't appear to be the case.

For example:

'autoSendPageView' => false,
'requireGaCookieClientId' => false,

A blank template still sends up with a Set-Cookie: _ia=….

A response with a Set-Cookie: header is often used an indicator to caching mechanisms that this response should not be cached. This includes static caches like Craft Cloud, Fastly, Varnish, Cloudflare.

In my example, IA is only being used for the Commerce event integration, but having the plugin enabled disabled static cache globally.

Have you tried using the createGclidCookie setting and setting it to false?

This will not cause IA to use the cookie and, instead, rely on ga4 cookie.

That seems to work!
