Shortening blog post address in browser - .htaccess

Question

I need to shorten address in browser in PrestaShop from "csblog/post" to "blog". Customer is using blog plugin "CS Blog" which generates both links and addresses.
csblog is module, post is controller.
scheme of address is /csblog/post/friendly-name
Already tried changing link and address schemes in plugin files and found where exactly it's done, but after changing module and controller - it crushes. It can't find posts or no page error shows.
Already tried various .htaccess Rewrite sentences in main app (in folder and in main folder of module. No effects.
No help in internet as this plugin seems not very popular.
This is my current code in .htaccess:
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ csblog/post/([^&\]+)
RewriteRule ^blog/%1? [L]
How can I make this short address, should it be done with .htaccess or managed only via plugin?
Function that generates links:
{
if (!$id_lang)
$id_lang = Context::getContext()->language->id;
$id_shop = Context::getContext()->shop->id;
$url = Context::getContext()->link->getBaseLink($id_shop).$this->getLangLink($id_lang, null, $id_shop);
$params['module'] = $module;
$params['controller'] = $controller ? $controller : 'default';
$dispatcher = Dispatcher::getInstance();
$dispatcher->addRoute('cs_blog_post', '{module}{/:controller}/{id_cs_blog_post}-{category_parent}-{rewrite}.html', null, 1, array(//{module}{/:controller}
'module' => array('regexp' => '[_a-zA-Z0-9_-]+', 'param' => 'module'),
'controller' => array('regexp' => '[_a-zA-Z0-9_-]+', 'param' => 'controller'),
'category_parent' => array('regexp' => '[_a-zA-Z0-9_-]+', 'param' => 'category_parent'),
'id_cs_blog_post' => array('regexp' => '[0-9]+', 'param' => 'id_cs_blog_post'),
'rewrite' => array('regexp' => '[_a-zA-Z0-9-\pL]*'),
), array('fc' => 'module',));
// If the module has its own route ... just use it !
if ($dispatcher->hasRoute('module-'.$module.'-'.$controller, $id_lang))
return Context::getContext()->link->getPageLink('module-'.$module.'-'.$controller, $ssl, $id_lang, $params);
else
return $url.$dispatcher->createUrl('cs_blog_post', $id_lang, $params);
}
Function that generates blog posts address:
public function hookModuleRoutes($params){
'cs_blog_post' => array(
'controller' => null,
'rule' => '{module}{/:controller}/{id_cs_blog_post}-{category_parent}-{rewrite}.html',
'keywords' => array(
'module' => array('regexp' => '[_a-zA-Z0-9_-]+', 'param' => 'module'),
'controller' => array('regexp' => '[_a-zA-Z0-9_-]+', 'param' => 'controller'),
'category_parent' => array('regexp' => '[_a-zA-Z0-9_-]+', 'param' => 'category_parent'),
'id_cs_blog_post' => array('regexp' => '[0-9]+', 'param' => 'id_cs_blog_post'),
'rewrite' => array('regexp' => '[_a-zA-Z0-9-\pL]*'),
),
'params' => array(
'fc' => 'module',
),
),
}

Answer 1

Routing is on your module's main file.
find function hookModuleRoutes on your file (probably csblog.php).
Then you can change your route

Answer 2

You might want to check on this expression to make sure if that would be the redirect you want to do. Then, you want to add a RewriteRul on your htaccess file. Maybe, something similar to this would work:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} csblog\/post [NC]
RewriteRule ^(.*)csblog\/post$ $1blog [NE,R=301,L]
</IfModule>
Options -Indexes -MultiViews
Ever time that you change your htaccess, you may want to clear your browsing history and test it to see if it works.
