What is a Server Error Log and How to Find 404 Errors in a Server Error Log
How do I find 404 errors in my server error log?
A server Error Log File for a webserver
is the file (commonly error_log in Unix and error.log
Windows) where the server sends diagnostic information
and records errors that it encounters while processing
requests. Generally it is the primary file to look
at when problems are encountered ranging from
document errors to scripting
or cgi errors. Error logs are essential to maintaining
visitor retention since they will indicate the
400 series of errors like the common 404 - Page
Cannot Be Found errors. In the case of a 404 error the
Web administrator or Webmaster can implement redirects
so that visitors will be directed to existing content while he/she fixes the broken URL link causing the problem.
