Need to improve how we handle URL routing in React front pages #15
Description
The current Backend implementation has multiple duplicate commands that return the same page for the URL routing of the react app.
In addition, due to the limitation of the redirect implementation of session auth, duplicate calls of session auth can also be checked.

It is necessary to clean up the URL routing method by referring to the link above and reimplement the code.
