# HTTP 508 Loop Detected

**Summary** — The server detected an infinite loop while processing the request.

## What it means

HTTP 508 Loop Detected (WebDAV) indicates the server detected an infinite loop while processing a request with "Depth: infinity". This prevents the server from being stuck in an endless cycle.

## Common causes

- Circular references in WebDAV collections
- Infinite redirect loops
- Self-referencing symbolic links
- Recursive server-side includes

## How to fix

- Check for circular references in your content
- Review redirect rules for loops
- Fix recursive includes or mounts

## SEO impact

Search engines cannot crawl content trapped in a loop. This effectively hides content from indexing.

## Monitoring tip

LemWatch detects redirect loops and infinite chains. It will alert you before search engines give up trying to crawl your content.
