TYPO3 Core

If you use an Apache 2.2 and the demo .htaccess the RewriteRule to resolve the verionNumberInFilename doesn't work. It seems like this is a bug in Apache 2.2 and/or mod_rewrite which appends the absolute path to the file when it rewrites the path. Or perhaps I misunderstood the Apache documentation ;-). In the browser you simply get a 404 for the CSS/Javascript file.

To solve this problem, you could set a "RewriteBase = /" in your .htaccess. Then it works for every file, which is not in the "/typo3" folder. But if you enable debugging for the backend, the CSS and Javascript files from the "/typo3" folder can not be found because of the .htaccess in the "/typo3" folder. You have to set a "RewriteBase = /typo3/" in the .htaccess file in the "/typo3" folder.

Or you have to modify the .htaccess RewriteRule in the root folder from

RewriteRule ^(.+)\.(\d+)\.(php|js|css|png|jpg|gif|gzip)$ $1.$3 [L]

RewriteRule ^(.+)\.(\d+)\.(php|js|css|png|jpg|gif|gzip)$ %{ENV:CWD}$1.$3 [L]

This bug doesn't happen with Apache 2.4, but i find no requirement for a specific Apache version on https://github.com/TYPO3/TYPO3.CMS/blob/master/INSTALL.md.

This bug appears in TYPO3 6.2 and 7.6. And I think (but have not tested it) it appears in 8.x, too.
