404 Bulunamadı

The HTTP 404 Not Found client error response code indicates that the server can't find the requested resource. Links which lead to a 404 page are often called broken or dead links, and can be subject to link rot.

A 404 status code does not indicate whether the resource is temporarily or permanently missing. But if a resource is permanently removed, a 410 (Gone) should be used instead of a 404 status.

Status

404 Not Found

Custom error pages

Many web sites customize the look of a 404 page to be more helpful to the user and provide guidance on what to do next. Apache servers can be configured using an .htaccess file and a code snippet like the following example.

ErrorDocument 404 /notfound.html

For an example of a custom 404 page, see MDN's 404 page.
