IframeHeaders

Set HTTP headers so your application can work inside an iframe, allowing cookie setting, etc. It deletes X-Frame-Options header, and add a fake P3P one.

Warning: This header combination could be considered insecure, so use it only for a good reason. This was made mainly to learn elixir.

Installation

1. Add iframe_headers to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:iframe_headers, "~> 0.1.0"}]
end
```

2. If you are using phoenix, you can put the plug in web/router.ex:

```elixir
pipeline :browser do
  plug IframeHeaders
end
```

Otherwise, ensure iframe_headers is started before your application:

```elixir
def application do
  [applications: [:iframe_headers]]
end
```

And use the plug at your needs

```elixir
plug IframeHeaders
```

Example

I made a simple server app to try it https://github.com/fleveque/iframe_headers_demo

Based on How to write a plug package and publish it on hex by Mark Connell. Nice tutorial to create your own plug package.
