# pingback

Publishes the address of the Pingback 1.0 endpoint that accepts link notifications for the current page.

## Code examples

Good example

```
<link rel="pingback" href="/xmlrpc.php">
```

Publishes a relative endpoint URL, which resolves against the page's base URL.

Avoid this example

```
<link rel="pingback">
```

Has no href, so it does not identify a Pingback endpoint.

## Recommendations

- 01 Secure the endpoint Pingback endpoints accept network requests derived from other sites. Protect them against spam, abuse, and server-side request forgery.
- 02 Do not invent an absolute URL rule HTML accepts relative URLs here and resolves them against the document base URL. Use an absolute URL only when it makes deployment clearer.
