# redirect-https # redirect-https
Redirect from HTTP to HTTPS. Secure-by-default redirects from HTTP to HTTPS.
Makes for a seemless experience to end users in browsers (defaults to `301 Permanent + Location` redirect) * Browsers get a 301 + Location redirect
and tightens security for apis and bots, without adversely affecting strange browsers (fallback to `meta` redirect). * Only developers, bots, and APIs see security warning (advising to use HTTPS)
* Always uses meta redirect as a fallback, for everyone
* '/' always gets a 301 (for `curl | bash` installers)
* minimally configurable, don't get fancy

## Advanced Options
For the sake of `curl | bash` installers and the like there is also the option to cause bots and apis (i.e. curl)
to get a certain redirect for an exact path match:
```js
{ paths: [
{ match: '/'
, redirect: 301
}
, { match: /^\/$/
, redirect: 301
}
]
}
```
If you're using this, you're probably getting too fancy (but hey, I get too fancy sometimes too).
