Custom headers are additional pieces of information that are sent along with the server’s response. You can use custom headers to convey specific information to the client, such as the server software version, content type, and caching settings.

Why do you need custom headers?

Custom headers can offer significant benefits for your website. Here are some reasons why you should consider using custom headers:

1.	Improve your website’s security
2.	Enhance your website’s performance
3.	Control caching behavior
4.	Communicate relevant information to the client

How to use Apache Server Cond Custom Header?

Using Apache Server Cond Custom Header is relatively easy. You need to create a new configuration file or modify the existing one to add custom headers. Here are the steps:

1. Create a file named “.htaccess” in your website’s root directory
2. Add the following lines to the file:

<IfModule mod_headers.c>
Header set Custom-Header "MyValue"
</IfModule>

3. Save the file and upload it to your website’s root directory
4. Test the custom header by sending a request to your website using a web browser or a tool like curl
