What is mod_rewrite?

Net Solution Hosting uses Apache, an open source HTTP server program, to host your sites. Apache can be customized via modules, one of the mod_rewrite modules that can: redirect a URL to another URL, rewrite required URLs, limit access to your site, and more.

A rewrite rule can be invoked by placing these rules in the .htaccess file. Below are examples where you can use these rules to customize the module according to your needs.

Notă: Please note that we do not support this code, nor do we promise to make this code for you. Some of these codes work in combination but others do not.
