Unreplaced variables in page metadata #27
Description
If we use variables in fields like page.description or page.og_description on pages with uncached content objects, the markers will be replaced only if the pages are not served from cache. If the request is answered with cached content, the raw markers will be visible in the page content.
In these cases, the html source passed to ext variables' ContentProcessor::replaceContent does not contain the rendered page head, but markers such as ###META88b79195bfbc33513067fe02b89e7336###. As the markers are not in the source yet, they cannot be replaced.
Content passed to ContentProcessor::replaceContent:
<!DOCTYPE html>
<html dir="ltr" lang="de-CH" class="no-js" prefix="og: http://ogp.me/ns#">
<head>
…

…I wonder conceptually if ext:variables is meant to replace variables in uncached parts of the page.
