Redirect Loop
01 Definition
Redirect Loop meaning: A broken redirect setup where URLs point back to each other and never reach a final page.
A redirect loop occurs when URL A redirects to URL B and URL B redirects back to A, or a longer cycle returns to its start. Browsers and crawlers detect this and stop, showing an error instead of content. The affected pages become unreachable and cannot be indexed.

Why it matters
How Redirect Loop fits the work
A loop makes a page completely inaccessible to users and search engines, so catching and breaking it quickly prevents lost traffic and indexing.
In context
A misconfigured rule sent the HTTPS page back to HTTP, which redirected to HTTPS again, so browsers showed a 'too many redirects' error.
Practical note
Loops often come from conflicting HTTPS, www, or trailing-slash rules; test redirect rules together, not in isolation, to catch cycles before they ship.
