Why WebLogin Can Break When SEO Strict URLs Are Enabled

Authentication and canonical URL enforcement both want to control redirects, so they need to be aligned carefully on login pages.

SEO Strict URL rules are useful until they collide with authentication flows. The old case here described a project where WebLogin stopped behaving correctly once strict URL handling was enabled.

Why the Collision Happens

login pages often depend on predictable POST and redirect flows
strict canonicalization may rewrite those requests unexpectedly
custom builds can add one more routing assumption on top

The practical lesson is simple: any auth page should be tested separately when SEO Strict logic changes. Canonical routing and login routing must agree, or one will break the other.
