Original Pull Request: https://github.com/langgenius/dify/pull/23937

State: closed
Merged: Yes

Fixes #23936

Summary

This PR resolves the user profile dropdown cache synchronization issue that occurs when quickly switching between main page and account page layouts.

Key improvements:

  • Fixed Response handling: Use Response.clone() to avoid bodyUsed state pollution across different AppContext instances
  • Enhanced SWR caching: Added global cache provider to enable data sharing between separate layout SWR contexts
  • Request optimization: Implemented deduplication (60s) and focus throttling (5s) to reduce redundant API calls
  • Error resilience: Added comprehensive error handling and fallback mechanisms

Technical details:

  • Resolves dual SWR context isolation by providing shared cache instance
  • Maintains 100% backward compatibility with zero breaking changes
  • Pure client-side optimization with no server impact

Screenshots

Before After
User dropdown shows blank info after quick page switching User info remains stable across all page transitions
