Apache web server with the mod_rewrite module

I installed a multisite WordPress, and it has a thing that I need: "Pretty permalinks".

So, that "Pretty permalinks" are available under:

* Apache web server with the `mod_rewrite` module
* Microsoft IIS 7+ web server with the URL Rewrite 1.1+ module and 
                                                        PHP 5 running as FastCGI
* Microsoft IIS 6+ using ASAPI_Rewrite
* Lighttpd using a 404 handler or mod_rewrite (see See Also)

I use a hosting, and just want to know (to test) if the hosting server supports this mod_rewrite or not.

Is there a way to find it out without admins help?

• Given your provider is using Apache httpd:

  Create an .htaccess file with the content RewriteEngine on. If you get an internal server error when opening your site in a web browser, mod_rewrite is not installed or you're not allowed to use these directives in an .htaccess file.
