Choosing the right permalink structure for your blog is a big decision. It is not something you want to change everyday so you may as well get it right the first time. You can certainly use your .htaccess file to change the behavior of your website too (e.g. run 301 redirects). Many of these things can be done without a plugin. WP htaccess Control happens to be a tool that could save you time making changes to your permalinks and .htaccess file.
WP htaccess Control provides you with an interface to change your permalinks and .htaccess file. You can make major changes to your URL structure (including the URLs for your author and regular pages). Changing the URL structure of archive pages is supported too.
WP htaccess ControlÂ lets you define custom .htaccess directives or make changes to the default WordPress .htaccess file. Want to protect your wp-config by making changes to this file? This plugin supports that. Disabling hot linking, directory browsing, and server signatures on your pages can be done with a couple of clicks. Of course, you can make other changes to your .htaccess file from within this plugin.
All in all, if you don’t want to manually edit your .htaccess file, this plugin provides you with an interface to make the changes you need.
