# Xamarin WebView With Custom Headers

An example that shows how to send request headers in a Xamarin Webview using custom renderers. An example that shows how define custom headers values from shared code is also included.

## Simple version

The request is filled with a custom header which then can be fetched in the website scanning the request's headers:

### Android

Android requires the `INTERNET` permission in order to load a website from the Internet.

Basically, you need to define a `WebViewClient` and override the `ShouldOverrideUrlLoading(WebView view, string url)` function, then set the headers and perform the request calling `View.LoadUrl(url, headers)`.

### iOS

iOS doesn't require any special configuration.

```
var headerKey = new NSString("A-custom-header");
var headerValue = new NSString("a custom value");
var dictionary = new NSDictionary(headerKey, headerValue);

webRequest.Headers = dictionary;
```

## Defining custom headers values from shared code

If you want to assign a custom value from shared code to each renderer, take a look at the `CustomWebView` control and `CustomWebViewPage` view to see how to achieve this. Basically, we're using Xamarin.Forms custom controls and data bindings to define custom parameters and get the value in each custom renderer.
