wordpress 404错误页面问题

Question

I am working on a wordpress website and the permalinks are set to default ie like http://www.example.com/?p=213 . If the page Id or Post Id is not valid then only it goes to the 404.php file of my theme else if I try to check 404 page for some random page like http://www.example.com/somepagename then It takes me to the host's 404 error page. How do I make this go to my theme's 404 page as well ? It is a trouble, I hope you guys will help me out here. Thank You in advance

About short heads up on HTTP Request Processing

The HTTP request is processed in the following sequence

1. Browser sends a request to server
2. Server receives the request
3. Checks for the Page requested
   IF FOUND
   Display Page
   IF NOT FOUND
   Display 404 Page
   

What's happening under the hood

In case of http://www.example.com/?p=213 the page is found in the server hence the server doesn't display the 404 page. However, when wordpress processes the query string p=213 , it identifies that no such page/post exists and displays the wordpress 404 page.

In case of http://www.example.com/somepagename the page is not found in the server hence the server itself displays the 404 page even before wordpress can process it.

Solution

You have to make the 404 page of the wordpress (appropriate 404 for the selected theme) as the 404 page of the webserver too. You can also link a php page to the webserver error message which would redirect to appropriate 404 pages based on themes and other factors.
