Unknown WordPress htaccess tips & tricks

What is the .htaccess file?

.htaccess is a configuration file for use on web servers running the Apache Web Server software. .htaccess files can be used to alter the configuration of the Apache Web Server software to enable/disable additional functionality and features that the Apache Web Server software has to offer. It includes basic redirect functionality. for instance, if a 404 file not found error occurs, or for more advanced functions such as content password protection or image hotlink prevention.

How to use the .htaccess file?

.htaccess files provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

When to use the .htaccess file?

The .htaccess file should be used when the main server configuration file cannot be accessed or modified. It is always best to use the server configuration files over .htaccess files.

The following htaccess will able to help you to achieve a simple task such as redirection and web server optimization;
