404 ERROR

We every one know that when we request a page that doesnt exist we are given "404 error" but very rarely we know about it. most of us are unknown about the meaning of it.
So to remove the confusion this page is for you

404

1. A 404 is an HTTP status code often displayed as either "Not Found 404" or "Page Not Found" and is an indication that the web server exists, but the page you are attempting to access, does not. When this occurs it is an indication that theweb page has moved, been deleted, or is currently being updated. Below is an example of how a generic 404 error message may look on a web page.

Creating a custom 404 page

If you run your own website or blog it is essential that you create a custom 404 page to help direct visitors who encounters this error. If you have access to the .htaccess file and want to create a custom 404 error page add the below line into your .htaccess file. In the example below, any time a visitor encounters a 404 error they are directed to the my_404.htm page. If you have a web based Control Panel, such as cPanel, your 404 error pages can also be customized in that Control Panel.
ErrorDocument 404 /my_404.htm

Tips on creating a smart 404 error page

  • At the very least, make sure your 404 error page has links to other sections of your site. One good example is a link to your site map.
  • If your site or blog has a search engine, make sure it is visible on the 404 error page.
  • If you are using Google Analytics, setup error tracking so you can know about your 404 errors. 404 errors are also in the Google Webmaster tools.
  • If you are familiar with a scripting language, instead of referring a static 404 page make it dynamic. For example, the Computer Hope 404 page logs each error, runs the URL through an algorithm to suggest a recommended page, and finds keywords in the URL to be used in the search box.
Tip: If you are a webmaster and have moved a web page to an alternate location use a 301 error code. If you have removed something with no intentions of returning it use a 410
