In WordPress, a web page request refers to the process of a user accessing a specific web page on a WordPress website. When a user enters a URL or clicks on a link to visit a page, their web browser sends a request to the web server hosting the WordPress site, requesting the content of that particular page.

Here’s a simplified overview of how a web page request is handled in WordPress:

1. User enters a URL or clicks on a link: When a user wants to visit a specific page on a WordPress site, they enter the URL of that page in their web browser or click on a link that points to the desired page.
2. HTTP request sent: The user’s web browser sends an HTTP request to the web server where the WordPress site is hosted. The request contains information such as the requested URL, the request method (typically GET for page requests), headers, and other data.
3. Web server receives the request: The web server, such as Apache or Nginx, receives the HTTP request from the user’s browser.
4. WordPress routing: The web server passes the request to WordPress. This can be done using various methods like mod_rewrite in Apache or URL rewriting in Nginx. WordPress examines the requested URL and determines which WordPress template or handler should handle the request.
5. Querying the database: Once the appropriate template or handler is identified, WordPress queries the database to retrieve the content for the requested page. The database stores the page’s content, including text, images, and other media.
6. Building the web page: WordPress retrieves the necessary data from the database and uses the selected template or handler to generate the HTML markup for the web page. This includes inserting the retrieved content, applying the website’s theme styles and layout, and rendering any dynamic elements.
7. Web server delivers the response: Once the web page is constructed, WordPress sends the generated HTML markup as a response back to the web server.
8. Response sent to the user: The web server transmits the response back to the user’s web browser.
9. Web page rendered in the browser: The user’s web browser receives the response and renders the HTML markup, displaying the requested web page to the user.

Throughout this process, WordPress also allows various hooks and filters that developers can utilize to modify or extend the behavior of the page request, such as adding custom functionality or modifying the content before it is rendered.

It’s important to note that this is a simplified explanation of the web page request process in WordPress, and there can be additional steps or variations depending on the specific WordPress setup, plugins, caching mechanisms, and server configurations.
