How to redirect a page with `.htaccess`?

To redirect a page using `.htaccess`, you must create or edit the `.htaccess` file in the root directory of your website. This file uses Apache’s mod\_rewrite module to handle URL redirections. Here are several ways to achieve different types of redirects:

301 Redirect (Permanent)
A 301 redirect signals to search engines that the page has been permanently moved to a new location. This is the most commonly used type of redirect for SEO purposes. To add a 301 redirect in your `.htaccess` file, use the following syntax:

```
Redirect 301 /old-page.html http://www.yourwebsite.com/new-page.html
```

Example:
```
Redirect 301 /about.html http://www.yourwebsite.com/about-us.html
```

302 Redirect (Temporary)
A 302 redirect is used when a page is temporarily moved. It doesn’t pass link equity like a 301 redirect, but it’s useful if the page is going to be back at its original URL at some point.

```
Redirect 302 /temporarily-moved-page.html http://www.yourwebsite.com/new-temporary-page.html
```

Example:
```
Redirect 302 /sale.html http://www.yourwebsite.com/summer-sale.html
```

Redirect with mod\_rewrite
For more complex redirects, you can use mod_rewrite to create rules using regular expressions. Ensure that the mod_rewrite module is enabled. Add the following lines at the top of your `.htaccess` file to enable rewrite:

```
RewriteEngine On
```

Redirect a Single Page
```
RewriteRule ^old-page.html$ http://www.yourwebsite.com/new-page.html [R=301,L]
```

Example:
```
RewriteRule ^contact.html$ http://www.yourwebsite.com/get-in-touch.html [R=301,L]
```

Redirect an Entire Directory
If you want to redirect an entire directory to a new location, use the following rule:

```
RewriteRule ^old-directory/(.*)$ http://www.yourwebsite.com/new-directory/$1 [R=301,L]
```

Example:
```
RewriteRule ^blog/(.*)$ http://www.yourwebsite.com/news/$1 [R=301,L]
```

Redirect All Pages to a New Domain
This rule will redirect all traffic from the old domain to a new domain:

```
RewriteCond %{HTTP_HOST} ^old-domain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.old-domain.com$
RewriteRule (.*)$ http://www.new-domain.com/$1 [R=301,L]
```

Example:
```
RewriteCond %{HTTP_HOST} ^example-old.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.example-old.com$
RewriteRule (.*)$ http://www.example-new.com/$1 [R=301,L]
```

Redirect Non-www to www (or vice versa)
To standardize URLs and avoid duplicate content issues, you might want to redirect all your non-www traffic to www (or vice versa).

Non-www to www:
```
RewriteCond %{HTTP_HOST} ^yourwebsite.com [NC]
RewriteRule ^(.*)$ http://www.yourwebsite.com/$1 [L,R=301]
```

www to Non-www:
```
RewriteCond %{HTTP_HOST} ^www.yourwebsite.com [NC]
RewriteRule ^(.*)$ http://yourwebsite.com/$1 [L,R=301]
```
