### `Link` header ### Pagination Link header
[Link headers](http://www.w3.org/wiki/LinkHeader) are sent back with each response. These have `rel` prev/next/first/last and contain the relevant URL. Please use these instead of generating your own URLs. [Link headers](http://www.w3.org/wiki/LinkHeader) are sent back with each
response. They have `rel` set to prev/next/first/last and contain the relevant
URL. Please use these links instead of generating your own URLs.
Example of `Link` header (line breaks added for clarity): In the cURL example below, we limit the output to 3 items per page (`per_page=3`)
and we request the second page (`page=2`) of [comments](notes.md) of the issue
with ID `8` which belongs to the project with ID `8`:
```bash
curl -I -H "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v3/projects/8/issues/8/notes?per_page=3&page=2
``` ```
$ curl -I -H "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" \
