## The back-half

The back-half is the part after the last slash. Choose it yourself, or leave it empty and Linkaloo makes a random one of seven characters. Random ones leave out letters that look alike, such as 0 and O. Some words are reserved and cannot be used.

## 302 or 301

You choose per link. **302** is the default and says the link may point somewhere else later. **301** tells browsers and search engines the move is permanent.

## Edit, pause, delete

- **Edit** changes the destination, the title and the tags. The short link stays the same.
- **Pause** stops the link without deleting it. A paused link answers 404.
- **Delete** removes the link. You type the back-half again to confirm.

## What the link answers

| Situation | Answer |
| --- | --- |
| The link exists | The redirect (302 or 301) |
| The link is missing or paused | 404 |
| The link was taken down | 410 |
| Linkaloo cannot be reached | 503, never a redirect somewhere else |
