Page Not Found

404 Error. Go Back to Snyders.US

404 File Not Found is a message in the case of a "404 error"; it appears in most web browsers when the connection works, and the first part of the URL correctly leads to a working web server, but the rest of the URL specifies a page that does not exist on the server.

The 404 error is one of the standard response codes of the web's HTTP protocol. The first 4 indicates a client error such as a mistyped URL. The middle 0 refers to a general syntax error. The last 4 just indicates the specific error in the group of 40x, which in this case is "URL Not Found".

The use of three-digit codes is similar to the use of such codes in earlier protocols such as FTP and NNTP. These errors can be customized on a large number of such servers, such as Apache, to display a page that could be of more help than a default. Internet Explorer will not read these pages, however, unless they are larger than 512 bytes.
