Session Lost After Replit Restart
Users are logged out when your Replit app restarts or scales. Session data stored in memory is lost, forcing users to re-authenticate. This is critical for production apps.
Replit deployments can restart unexpectedly, and memory-based sessions don't persist across those events.
Common Causes
- Sessions stored in-memory instead of persistent storage
- No session database configured
- Redis session store not connected or credentials missing
- PostgreSQL sessions table not created
- Session timeout too short or not configured
How to Fix It
Switch from memory-based sessions to a database backend. Use Replit's PostgreSQL or connect to Redis. For Spring Boot, configure spring.session.store-type=jdbc or =redis with appropriate datasource properties. Ensure the sessions table exists and database credentials are in Replit Secrets.

Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)
Alvin Voo
I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Get HelpFrequently Asked Questions
What's the easiest way to persist sessions?
Use Replit's built-in PostgreSQL and configure Spring Session JDBC storage
Do I need Redis for sessions?
No, PostgreSQL works fine for most apps. Redis is better for high-traffic scenarios
