## Goth Needs a New Maintainer
[https://blog.gobuffalo.io/goth-needs-a-new-maintainer-626cd47ca37b](https://blog.gobuffalo.io/goth-needs-a-new-maintainer-626cd47ca37b) - TL;DR: I, @markbates, won't be responding to any more issues, PRs, etc... for this package. A new maintainer needs to be found ASAP. Is this you?

## Security Notes
By default, gothic uses a `CookieStore` from the `gorilla/sessions` package to store session data.
As configured, this default store (`gothic.Store`) will generate cookies with `Options`:
```go
&Options{
Path: "/",
Domain: "",
MaxAge: 86400 * 30,
HttpOnly: true,
Secure: false,
}
```
To tailor these fields for your application, you can override the `gothic.Store` variable at startup.
The follow snippet show one way to do this:
```go
key := "" // Replace with your SESSION_SECRET or similar
maxAge := 86400 * 30 // 30 days
isProd := false // Set to true when serving over https
store := sessions.NewCookieStore([]byte(key))
store.MaxAge(maxAge)
store.Options.Path = "/"
store.Options.HttpOnly = true // HttpOnly should always be enabled
store.Options.Secure = isProd
gothic.Store = store
```
