- What is mrsuh/nginx-session-handler and how does it work with Laravel?
- mrsuh/nginx-session-handler is a PHP session handler that reads and writes session data in a format owned by an out-of-tree nginx module, so nginx can inspect sessions directly from shared memory. It is not a Laravel session driver; in Laravel you would wrap it in an adapter implementing SessionHandlerInterface and register that adapter through Session::extend. The package is a thin PHP-side reader/writer, while nginx is effectively the primary session authority. Treat it as a specialized nginx integration rather than a drop-in Laravel package.
- Is mrsuh/nginx-session-handler a native Laravel session driver?
- No. It is a raw PHP SessionHandlerInterface-shaped component and does not register itself with Laravel's SessionManager or provide a native driver. Laravel expects one authoritative session store accessed through its session stack, whereas this package assumes nginx owns and writes session state. You would need a custom driver adapter and Laravel session contract tests before using it.
- How do I install and integrate nginx-session-handler in Laravel?
- Install the package with Composer, then create a class such as App\Sessions\NginxSessionHandler that implements SessionHandlerInterface and delegates open, close, read, write, destroy, and gc to the package. Register it with Session::extend('nginx', ...) in a service provider and set config/session.php driver to nginx only after contract tests pass. You also need a compatible nginx build, a shared filesystem path visible to nginx and php-fpm, and a decision about nginx's session cookie versus Laravel's {app}_session cookie.
- Does mrsuh/nginx-session-handler support Laravel 10 and Laravel 11?
- The package has no documented Laravel compatibility statement and is not a Laravel driver, so Laravel 10/11 support depends on your adapter rather than the package itself. A plausible target is Laravel 10 or 11 on PHP 8.1+ with nginx and php-fpm, but you must verify PHP 8.2/8.3 and current nginx compatibility yourself. There is no CI signal or compatibility matrix to rely on.
- What nginx module do I need to build for nginx-session-handler?
- You need the matching out-of-tree nginx module that defines the shared-memory session format the PHP package reads and writes. It is not available in distro packages or standard nginx Docker images, so you must own an nginx build and deployment pipeline. Version mismatch between the module and the PHP package is a silent data-corruption risk, so pin and test both together.
- Can nginx and php-fpm share sessions across separate containers?
- Yes only if both processes can see the same session storage path; in separate nginx and php-fpm containers that usually means a shared volume or sidecar. That is a meaningful architectural change for a conventional Laravel deployment. If you cannot provide a shared filesystem path visible to both, the package's model does not fit.
- How does nginx-session-handler handle concurrent session writes and locking?
- The available assessment says locking semantics are unverified and are the highest-risk unknown. PHP's native session locking, flock behavior, and journal replay are not confirmed, and the package may rely on nginx-side atomicity instead. Before commitment, test concurrent requests to the same session and confirm whether the on-disk format is versioned and can reject an incompatible journal.
- Is mrsuh/nginx-session-handler safe for production use?
- Treat it as prototype-grade until proven otherwise: it has effectively zero adoption, one maintainer, a last release in May 2023, and no evident security disclosure process or CI signal. The biggest risks are binary-format coupling to the nginx module and unverified session locking. Do not put it in production without a spike, contract tests, a fork plan, and a named owner for the nginx module build.
- Can I migrate existing Laravel file or Redis sessions to nginx shared memory?
- There is no documented import path from file, Redis, or database session drivers, and the nginx session format is opaque. That means no incremental migration; you would need a custom export/import bridge or accept a session reset at cutover. Validate the format and locking behavior first rather than assuming a drop-in migration.
- What are alternatives to nginx-session-handler for fast Laravel auth checks?
- If the real goal is nginx-side auth gating or routing based on session state, consider designs where nginx checks a lightweight token or cache while Laravel remains the authoritative session store. Standard Laravel drivers such as Redis, database, or file sessions keep one source of truth and avoid a second session authority. The package is most defensible only when nginx must read sessions directly and you can own the module build and shared storage.
