# Managing Page Redirection and Browsing History Navigation
## History Navigation
When a user clicks a web page link on the frontend page, the **Web** component automatically opens and loads the target website by default. When the current page is assigned a new loading link, the address of the accessed web page is automatically recorded. You can call [forward()](../reference/apis/js-apis-webview.md#forward) or [backward()](../reference/apis/js-apis-webview.md#backward) to browse the previous or next history record.
In the following example, when a user clicks the button, **backward()** is called to go back to the previous page.
```ts
// xxx.ets
import web_webview from '@ohos.web.webview';
@Entry
@Component
struct WebComponent {
webviewController: web_webview.WebviewController = new web_webview.WebviewController();
build() {
Column() {
Button('loadData')
.onClick(() => {
if (this.webviewController.accessBackward()) {
this.webviewController.backward();
return true;
}
})
Web({ src: 'https://www.example.com/cn/', controller: this.webviewController})
}
}
}
```
If a previous record exists, [accessBackward()](../reference/apis/js-apis-webview.md#accessbackward) will return **true**. Similarly, you can call [accessForward()](../reference/apis/js-apis-webview.md#accessforward) to check whether a next record exists. If you skip the check, [forward()](../reference/apis/js-apis-webview.md#forward) and [backward()](../reference/apis/js-apis-webview.md#backward) will not trigger any action if the user has navigated to the end of history records.
## Page Redirection
The **Web** component provides the [onUrlLoadIntercept()](../reference/arkui-ts/ts-basic-components-web.md#onurlloadintercept) API to redirect you from one page to another.
In the following example, the frontend page **route.html** is loaded on to the application home page **Index.ets**, and the user is redirected to the application page **ProfilePage.ets** when clicking the link on the **route.html** page.
- Code of the **index.ets** page:
```ts
// index.ets
import web_webview from '@ohos.web.webview';
import router from '@ohos.router';
@Entry
@Component
struct WebComponent {
webviewController: web_webview.WebviewController = new web_webview.WebviewController();
build() {
Column() {
Web({ src: $rawfile('route.html'), controller: this.webviewController })
.onUrlLoadIntercept((event) => {
let url: string = event.data as string;
if (url.indexOf('native://') === 0) {
// Redirect to another page.
router.pushUrl({ url:url.substring(9) })
return true;
}
return false;
})
}
}
}
```
- Code of the **route.html** page:
```html
```
- Code of the **ProfilePage.ets** page:
```ts
@Entry
@Component
struct ProfilePage {
@State message: string = 'Hello World';
build() {
Column() {
Text(this.message)
.fontSize(20)
}
}
}
```
## Cross-Application Redirection
The **Web** component supports redirection from one application to another.
In the following example, when a user clicks the link on the frontend page **call.html**, the user will be redirected to the dial screen of the phone app.
- Application code:
```ts
// xxx.ets
import web_webview from '@ohos.web.webview';
import call from '@ohos.telephony.call';
@Entry
@Component
struct WebComponent {
webviewController: web_webview.WebviewController = new web_webview.WebviewController();
build() {
Column() {
Web({ src: $rawfile('xxx.html'), controller: this.webviewController})
.onUrlLoadIntercept((event) => {
let url: string = event.data as string;
// Check whether the link is redirecting to the dial screen of the phone app.
if (url.indexOf('tel://') === 0) {
// Redirect to the dial screen.
call.makeCall(url.substring(6), (err) => {
if (!err) {
console.info('make call succeeded.');
} else {
console.info('make call fail, err is:' + JSON.stringify(err));
}
});
return true;
}
return false;
})
}
}
}
```
- Code of the **call.html** page:
```html
```
