    This tutorial will help us in learning how to create error pages in apache. We can customize the error pages based on different error codes that is writen in Apache server's Directive ErrorDocument Follwoing are the Three digit error code:

    Apache error codes (401, 403, 404, 412, 500)


    If we come accross an error , we can handle it in four ways as below:

    1. Display a simple hardcoded error message
    2. Display a customized message
    3. Handle the problem by redirecting to an external URL
    4. Handle the problem by redirecting internally a local URL-path

    Note: The first option is default one and the 2-3 options are configured using the ErrorDocument Directive.


    Let us create a custom error page for error code 404 (i.e. file not found error)

    Step 1: First write an html page, say index.html to display the error message

    Step 2: Now place this file inside the site's root directory

    For example : path is = /var/www/html/projectrootdirectory/index.html
    
    if we place this index.html file in some other subdirectory say Error
    
    path = /var/www/html/projectrootdirectory/Error/index.html
    

    Step 3: Now include apache server's directive ErrorDocument in the .htaccess file with the syntax as below:

      ErrorDocument error-code action
    
        1. ErrorDocument : it is the Directive
        2. error-code : (i.e. any of the 401, 403, 404, 412, 500)
        3. action : the path of your custom error page.
    

    Note: for default action we can just write a message in a single quotes

    OR

    Find your Web server configuration file i.e. httpd.conf. In case of apache server your path will be

             /etc/apache2/apache2.conf
    

    For Example: We can create custom error page for a site under following path

    /etc/apache2/sites-enabled/000-default.conf

    Below is the code that we will write in the 000-default.conf file

           <VirtualHost *:80>
                  ServerAdmin admin@firstexample.com 
                  ServerName firstexample.com
                  ServerAlias www.example.com
                  DocumentRoot /var/www/firstexample/public&#95;html
                  ErrorDocument 404  /ErrorPages/404pagenotfound.html
    
                   # Other directives here
              </VirtualHost>
    

    Similarly we can maintain custom errror pages for the following error code 401, 403, 412, 500
