Or you can use domain cookie if you’re asking only and specifically about subdomain sites. Something like this Remember that cookies have size limits though.
How to transfer session IDs across different domains?
Since your websites are on different domains the session cookie does not transfer over, so that’s one thing that prevents cross-domain sessions from working. One technique to have the session ids transfer over is to append them to the query string of all your requests (PHP even has some degree of built-in support for this).
How to preserve session variables across different subdomains?
You can set https if you have SSL Connection. You must allow PHP to share same sessions for different subdomains before session_start () If you have access to php.ini then set it once there then you won’t need to set above lines in your PHP Files.
How are session IDs passed around in PHP?
Session ids are passed around using cookies by default. Since your websites are on different domains the session cookie does not transfer over, so that’s one thing that prevents cross-domain sessions from working.
How to save PHP sessions across sub domains?
If domain and subdomains point to different machines, the common storage (like database) is best for saving and restoring session data (I didn’t test yet). Use session_set_save_handler to do that. I know this is old but this works fine for me with multiple domains and sub domains on the same box.
Can a session id represent the same session state?
You are missing something: as long as those application share the same session state storage, the same session-id will represent the same session state. As session cookies in general are bound to domain on the client, you only need to pass session id when traversing the application boundaries.
Can you store cookies in a subdomain?
Http protocol doesn’t allow cookies/sessions to be stored on a domain without .tld (ie localhost won’t work, but stuff.localhost will). EDIT: Also make sure you always clear your browser cookies while testing/debugging sessions across subdomains.
Can we share domain namespaces across Microsoft 365 tenants?
Can we share domain namespaces across Microsoft 365 tenants? No. Organization domain names, such as fabrikam.com or tailspintoys.com, can only be associated and used with a single Microsoft 365 tenant. Each tenant must have its own namespace. UPN, SMTP, and SIP namespaces cannot be shared across tenants.
Storage: In Microsoft 365 licensing plans, software boundaries and limits for SharePoint Online are managed separately from mailbox storage limits. Mailbox storage limits are set up and managed by using Exchange Online. In both scenarios, storage can’t be shared across tenants.
