If the website on the virtual host has 404, 503 and other access errors, the webmasters need to understand the reasons for their appearance and the quick solution.

404 error is usually caused by:

404 error appears on the website, indicating that the page does not exist.

This situation is likely due to changes in website URL generation rules, renaming or moving of web pages, misspelling of imported links, etc., resulting in the original URL address being inaccessible.

When the Web server receives a similar request, it will return a 404 status code, telling the browser that the requested resource does not exist.

1) The Web site cannot be accessed on the requested port.

2) Web service extension lockdown policy blocks this request.

3) MIME mapping policy blocks this request.

Therefore, we need to set up a 404 error page for the website to improve website optimization and enhance user experience. We need to pay attention to several issues when setting up:

1) Do not redirect the 404 error to the homepage of the website, otherwise it may cause the homepage to disappear in search engines.

2) Do not use absolute URLs, if you use absolute URLs, the status code returned is 302+200.

3) 404 page does not automatically jump, let the user decide where to go. This involves the production of 404 pages, and the user experience is very important.

4) 404 page setup completed, be sure to check whether it is correct. HTTP header information must return a 404 status. This is mainly related to search engines, because if your website produces more pages, but the search engine sees a lot of the same normal pages, it may be mistaken for cheating.
