TYPO3 Core

You can reproduce this in TYPO3 6.2.3 with a setup like this:


page = PAGE
page {
10 = TEXT
10.value = Hello1
includeCSS {
file1 = EXT:myext/screen.css
}
}


the two hosts: extdev.domain.de, extdev-multi.domain.de

Copy this in the other root page,too and then make sure you have two domains (one as a folder and the other with a symlink to the same folder).

Example:

/www/extdev
/www/extdev-multi (symlink to /www/extdev)

1. Delete Cache in Install-Tool
2. Call the domain extdev-multi.domain.de - and you see the screen.css is included.
3. Call the domain extdev.domain.de - and there is no screen-css included.

The function \TYPO3\CMS\Core\Utility\PathUtility::stripPathSitePrefix(self::extPath($key) creates a relative path with the current PATH_site constant and a cached package path value with a substring. After clearing the cache - in the first step - TYPO3 produces a path depending on the host of extdev-multi.domain.de: with PATH_site = /www/extdev-multi.

This leads to cached package path like this: /www/extdev-multi/htdocs/typo3conf/ext/myext/

Calling extdev.domain.de stripPathSitePrefix() the value of PATH_site is now: /www/extdev/.

Now we have a cached package path with extdev-multi but the substring happens with the string length of /www/extdev/.

The expected relative path would be: "typo3conf/ext/myext/screen.css"

but the actual result is now: "htdocs/typ3conf/ext/myext/screen.css"
