How would you identify redirect loops?
A redirect loop occurs when:
A → B
B → A
or a longer cycle exists.
Use:
- crawler exports;
- HTTP request traces;
- automated redirect-chain checks;
- server logs.
Validate every old URL after deployment.
A migration should be tested before changing DNS or canonical infrastructure at scale.
