Cascade Created Login Redirect Loop
After Cascade refactored your authentication flow, users get caught in infinite redirects between login and home page. The session is created but the redirect logic continuously checks for authentication and loops back.
This typically happens when Cascade modified session validation, redirect filters, or authentication success handlers without properly understanding the existing flow.
Error Messages You Might See
Redirect from localhost:8080/login to localhost:8080/home to localhost:8080/login
Too many redirects
This page isn't redirecting properly
Common Causes
- Cascade modified AuthenticationSuccessHandler without preserving original redirect URL logic
- Session validation middleware added by Cascade runs after authentication, rejecting valid sessions
- Cascade removed conditional checks that determined when redirect should happen
- CSRF token validation conflicts with session creation in new auth flow
How to Fix It
Review the git diff for changes to WebSecurityConfig, authentication controllers, and filter chains. Look for removed conditional logic around session checks. Cascade may have simplified the logic incorrectly. Restore original session handling and ensure the authentication success handler sets the correct redirect target without looping.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

How do I debug redirect loops?
Check browser console Network tab for redirect chain. Look at WebSecurityConfig permitAll() rules to ensure /login is accessible without authentication.
Why did Cascade create this?
Cascade may have tried to add security checks without understanding the existing authentication success handler flow.
