[Question] I can't forget a specific URL

[Psabot]

Hello,

I have an issue on my side I can't wrap my head around.

I used the middleware on the following route

Route::get('/post/{slug}', [BlogController::class, 'showPost'])->middleware('cacheResponse')->name('blog.showpost');
It works well, the response is cached when I hit http://mywebsite.com/post/example

Then, when I want to forget the cache for a specific URL, I'll call this function

public function forgetCache($slug): JsonResponse
    {
        ResponseCache::selectCachedItems()->forUrls('/post/'.$slug)->forget();
     ....
    }

But this code does not forget the URL with the specified slug ("example" as per my previous example) ... (it works well with ResponseCache::clear(); but I don't want to wipe everything)
The slug is obviously the same. I'm sure I'm missing something obvious but I don't understand what at this moment.

Any help would be appreciated ! Thanks a lot !

EDIT : it WORKS when I return an empty string in useCacheNameSuffix but I thought selectCachedItems was the way to get around the suffix ?

Hi, i have the same probleme but it dont work with :

ResponseCache::selectCachedItems()->usingSuffix('')->forUrls(
    route('players.name', ['name' => $name])
);

have you find another solution ?

hi, to solve this problem you can change hasher in config/responsecache.php to your own
Replacing this method in it

public function getHashFor(Request $request): string
{
$cacheNameSuffix = '';

return 'responsecache-' . hash(
'xxh128',
"{$request->getHost()}-{$this->getNormalizedRequestUri($request)}-{$request->getMethod()}/$cacheNameSuffix"
);
}

At least in my case the cache is shared by all users

also the route function with the argument absolute: false is handy to specify the route to be cleared
ResponseCache::forget([route('footer-items.index', absolute: false)]);

I also tried using tags, but it seems that with my version of redis and Laravel the flush function does not work (laravel 10, redis 7.4.0),

Cache::tags('my-tag')->put('my-key', 'my-value')

After calling
Cache::tags('my-tag')->flush()
I still get the value
Cache::tags('my-tag')->get('my-key')
