Detecting & Fixing Redirect Loops

Understand what redirect loops are and how to fix them before they break your site.

What is a Redirect Loop?

A redirect loop occurs when two or more URLs redirect to each other in a circular pattern, causing an infinite loop. When a user tries to access any URL in the loop, their browser gets stuck in an endless cycle of redirects and eventually times out.

Common Loop Patterns

Simple Two-URL Loop

URL A → redirects to → URL B
URL B → redirects to → URL A
Result: Infinite loop ∞

User tries to access A, gets sent to B, gets sent back to A, repeat infinitely.

Self-Referencing Loop

URL A → redirects to → URL A
Result: Immediate infinite loop

A page redirects to itself. The browser immediately detects this and shows an error.

Multi-URL Loop Chain

URL A → URL B → URL C → URL D → URL A
Result: Loop after 4 redirects

Longer chains take longer to detect but have the same problem.

Why Redirect Loops Happen

  • 1.Misconfigured Rules: Setting up redirects without properly testing them
  • 2.Bidirectional Redirects: Accidentally redirecting A to B and B back to A
  • 3.Plugin Conflicts: Multiple WordPress plugins creating conflicting redirects
  • 4.Server Config Issues: Incorrectly configured .htaccess or Nginx rules
  • 5.Incomplete Migrations: Redirecting old domain to new domain which then redirects back

How to Detect Redirect Loops

Browser Error

You'll see an error like "ERR_TOO_MANY_REDIRECTS" or "This page isn't working. Too many redirects."

Using Redirect Checker

Our tool will detect and show you exactly which URLs are causing the loop. You'll see the redirect chain and where it loops back.

Browser DevTools

Open DevTools (F12), go to Network tab, and watch the redirect chain. Look for URLs appearing multiple times.

Server Logs

Check your web server access logs to see redirect patterns and where traffic loops back.

How to Fix Redirect Loops

Step 1: Identify the Loop

Use Redirect Checker or DevTools to trace the exact URLs involved. Note which pages redirect to each other.

Step 2: Access Your Server

If it's a server issue, you may need SSH access to your server. If it's WordPress, disable plugins to isolate the problem.

Step 3: Fix the Redirect Rules

Remove the conflicting redirect rule. Make sure URLs redirect one-way to their final destination, not back to themselves.

Step 4: Test with Redirect Checker

Use our tool to verify the loop is fixed. The redirect chain should resolve to the final URL without looping back.

Step 5: Monitor

Periodically check for redirect loops using Redirect Checker to ensure they don't reappear.
