===Basics==
This is a module for the Apache webserver and rewrites requested URLs on the fly. It operates both in per-server context (Apache v2.x: ##apache2.conf##) and per-directory context (##.htaccess##). Detailed informations can be found on the [[https://httpd.apache.org/docs/2.4/mod/mod_rewrite.html Apache Module Homepage]].

So what does it to WackoWiki?
  1. mod_rewrite enabled: 
    * ##~http://www.example.com/Download##
  2. mod_rewrite disabled:
    * ##~http://www.example.com/?page=Download##

===Howto enable mod_rewrite==
Of course, you need an Apache webserver WackoWiki is running on, and the module mod_rewrite has to be installed and activated.

mod_rewrite in your Apache configuration file (http.conf oder apache2.conf):
**///apache/conf/http.conf//**

**deactivated**
%%#LoadModule rewrite_module modules/mod_rewrite.so%%
**activated**:
%%LoadModule rewrite_module modules/mod_rewrite.so%%

====AllowOverride All====
Make sure that your .htaccess files are **not ignored**: in your apache configuration file (http.conf or apache2.conf), make sure that for the directory where the wiki is:
%%AllowOverride None%%
is **not set**. Because then ((https://httpd.apache.org/docs-2.4/mod/core.html#allowoverride .htaccess files are ignored)).
%%AllowOverride All%%

===.htaccess==
If you have no privileges to edit the apache2.conf (e.g. you rent webspace) or simply you don't want to, you have to use the ##.htaccess##-method (don't forget the dot!) with the following content:

%%
# No user serviceable parts inside
# If you want to fix anything by tuning htaccess - you're possibly on the wrong path

<IfModule mod_env.c>
	SetEnv HTTP_MOD_ENV on
</IfModule>

<IfModule mod_rewrite.c>
	<IfModule mod_env.c>
		SetEnv HTTP_MOD_REWRITE on
	</IfModule>
	RewriteEngine on
	RewriteRule ^ index.php [QSA,L]
</IfModule>

<IfModule !mod_rewrite.c>
<FilesMatch \.php$>
	# Apache 2.4
	<IfModule mod_authz_core.c>
		Require all denied
	</IfModule>
	# Apache 2.2
	<IfModule !mod_authz_core.c>
		Order Allow,Deny
		Deny from all
	</IfModule>
</FilesMatch>

<FilesMatch "^(admin|index)\.php$">
	# Apache 2.4
	<IfModule mod_authz_core.c>
		Require all granted
	</IfModule>
	# Apache 2.2
	<IfModule !mod_authz_core.c>
		Order Allow,Deny
		Allow from All
		Deny from None
	</IfModule>
</FilesMatch>
</IfModule>
%%

This file is shipped with the WackoWiki package you downloaded, you find this file inside the Wacko folder. If you can't find it, just create it (Permission: -rwxr-xr-x).

===httpd.conf / apache2.conf==
If you want to edit the ##httpd.conf## / ##apache2.conf## file directly, please make sure to delete or rename the ##.htaccess## in your Wacko folder.
Now add the following lines to your configuration file:
%%
#Wacko URL-rewriting

    Options Indexes Includes FollowSymLinks MultiViews
    AllowOverride All
    RewriteEngine on
    RewriteRule ^ index.php [QSA,L]
    Order allow,deny
    Allow from all

%%
Restart your webserver to enable the modifications!

===Special cases===
special .htaccess files

====RewriteBase==
If your webserver's URLs are not directly related to physical file paths, you will need to use RewriteBase in every .htaccess file where you want to use RewriteRule directives. 
%%
RewriteBase /
%%
%%
RewriteBase /folder/
%%
e.g. .htaccess
%%
<IfModule mod_rewrite.c>
 RewriteEngine on

 RewriteBase /folder/

</IfModule>
%%
