MSAL token cache collisions happen in ASP.NET Core when concurrent multi-instance web apps access a shared SQL-backed distributed cache, causing inconsistencies and stale entries during app recycles. This triggers authorization errors and disrupts user authentication.

Handle MSAL distributed cache errors by configuring ASP.NET Core with a custom cookie event handler and SQL cache. This setup detects token cache collisions, implements automatic sign-out for error recovery, and prevents stale token entries from disrupting authentication.

Yes, this MSAL cache handling approach specifically works with SQL-backed distributed caches in ASP.NET Core. It detects and recovers from token conflicts during app recycles or high concurrency, making it ideal for multi-instance web applications experiencing token cache errors.

The best way to recover from MSAL token cache collisions is implementing robust error detection with a custom cookie event handler in ASP.NET Core. This manages automatic sign-out to maintain application stability and ensures seamless user authentication recovery.

Configure ASP.NET Core to use a custom cookie event handler and a SQL distributed cache. This setup automatically detects token cache collisions and recovers authentication, preventing authorization errors without requiring manual intervention.
