TYPO3 Core

Bug #96502

Updated by Reinhard Hiebl over 2 years ago

Hello, 
 i have to modify the canonical tag. I do this thru the ModifyUrlForCanonicalTagEvent.  
 But after cache it always keeps the canonical url from the first cached page. Maybe additionalHeaderData in general is affected. 
 Don't know its a bug or i am using something wrong. The PageTitleGenerator works fine. 

 *services.yaml* 
 NS\MyExt\EventListener\CanonicalListener is called only once. Looks like route arguments below not respected in the cache hash? 
 <pre><code class="yaml">services: 
   .... 
   NS\MyExt\EventListener\CanonicalListener: 
     tags: 
       - name: event.listener 
         identifier: 'ns/myext/canonical' 
         after: 'cs-seo/canonical' 
         event: TYPO3\CMS\Seo\Event\ModifyUrlForCanonicalTagEvent 
 </code></pre> 

 *Site config.yaml* 
 Looks like the my_ext_item_slug argument will not respected in the page cache hash?  
 This probably where the problem is. But why? 
 (I am using the Simple type because the data are fetched from an remove rest api) 
 <pre><code class="yaml">routeEnhancers: 
   MyExtItemDetail: 
     type: Simple 
     limitToPages: 
       - 1047 
     routePath: '/{my_ext_item_slug}' 
     requirements: 
       my_ext_item_slug: '^$|[a-zA-Z0-9-].*' 
     _arguments: 
       my_ext_item_slug: my_ext_item_slug 
 </code></pre>
