Unclear Documentation regarding Preview of Hidden Pages

[apus-0]

Following sentence can be found in the documentation:
"If your frontend application passes all cookies from backend correctly you should be able to preview content associated with the root domain."

In my case the backend user cookie is available in the frontend, but i got an 404. This makes sense cause i don't know how to pass the cookie information back to TYPO3 to get the data of the hidden page. I mean the fronted has to send the cookie data to the backend when fetching data? Or am I wrong?

Hi @apus-0, what domain setup do you have? You have something like api.your-site.tld (TYPO3) and your-site.tld (FE) or something different?

[apus-0]

first I tried api.your-site.tld (TYPO3) and frontend.your-site.tld (FE) and after your response I also tried api.your-site.tld (TYPO3) and your-site.tld (FE). both appoached didn't work for me. in both cases cookie was set in frontend by TYPO3 when previewing the page, but the in the end i got a 404 page

if your main domain is matching and you have setup TYPO3 is api.your-site.tld and fe app is your-site.tld just setup backend cookie (which allows you see hidden pages) to domain .your-site.tld and it should work :)

@apus-0 could you send some screenshots of your cookie setup? This would help I believe. We have tested this in several projects, so we can provide some assistance for you.

Thanks a lot for your replies and for your help.

I set up the cookie domain in the ext_localconf.php of my sitepackage to
$GLOBALS['TYPO3_CONF_VARS']['BE']['cookieDomain'] = getenv('HKC_COOKIE_DOMAIN');

which is
HKC_COOKIE_DOMAIN=.hkc-de.local

and when opening the backend, following cookie is set:

and by opening the fronted app, following cookie is set:

What came into my mind is that i am currently running the site on my local machine, in a docker environment and the domains are no "real" domains. they are only network aliases of docker. Maybe this causes the disfunctionality? At the moment i dont have a test system with "real" domains. But I am working on it. Maybe this solves the problem?

Please let me know, if i should provide further information regarding the set up.

Tank you in advance.
