Description

When a page has USER_INT or COA_INT objects and is delivered from cache, most of the meta tags are missing.

Steps to reproduce:
- Setup fresh TYPO3
- Single page with meta description and no_index=1
- following TypoScript:

page = PAGE
page.meta.keywords.field = keywords
page.meta.viewport = width=device-width,initial-scale=1
page.10 = TEXT
page.10.value = HELLO WORLD!
page.20 = USER_INT

This might be related to one of the following Bugs:

https://forge.typo3.org/issues/86012
https://forge.typo3.org/issues/63776

This outright kills pages on mobile. Safari on iOS displays the Desktop website when the viewport-meta tag is missing!

I tested this on 9.4.0 and on current master (1ff01bcb74a4ce73493bce0969222b02e5e85add).

I am not sure, if Category SEO is correct. I think the main issue here is that the cached version of a page is different depending if there are *_INT objects on a page or not.

If the page has USER_INT-object, the cached content looks like this (data in cf_cache_pages):

<!DOCTYPE html>
<html lang="en">
<head>

<meta charset="utf-8">

If the page does not have the USER_INT object, the cached data looks like this:

<!DOCTYPE html>
<html lang="en">
<head>

<meta charset="utf-8">

This is also responsible for the other two bugs (#86012 related to indexed_search and #63776: hooks working on favicon for example).

Of course it's possible to just fix the meta-tags issue, but I believe it's better to fix the underlying issue.

Hi,

The underlying issue is IMHO no general issue, yes in case there are USER_INT objects on a page, the page is cached and rendered differently. We won't "fix" that behaviour, as that is not a bug. In case of a cached page the whole page should be cached without any markers whatsoever and directly delivered from cache (It's not only a bit slower to replace marker, its multiple times slower on a fully cached page).

On a page with USER_INT objects the basic skeleton of the page gets cached and only the marker replacement parts get rerendered on each subsequent request. So basically the flow has three different states:

uncached (completely new generation of everything),
page itself cached but has USER_INTs and
fully cached page

so, that behaviour is no bug. The bug in this case is actually, that the meta tags are missing - because the header section is constructed more or less separately iirc. I'll take a look at the other bugs, soon.

Had the same with title tag. I will fix this for meta tags.

Currently in TYPO3 9.5.1 pages, which contains a none cached plugin as content element (fx EXT:news searchform) have correct meta tags just for a given time. After some hours, all meta tags are missing again, except generator=TYPO3 CMS.
This breaks at least mobile websites, which depends on meta tag viewport data.

I thought, this was fixed for me as well. But after looking at the cache-expiration, I believe Joerg is correct and the metatags could disappear after a while (see attached screenshot).

The metatags are cached shorter than the page HTML
