I am using Apache 2.4.7 on Windows (the problem seems not to be existant in Apache 2.2). I have a problem with the internal redirection to a prerendered file. The file exists on the disk, but is not output by apache.
In the vhost config I have (excerpt):
DocumentRoot "C:/xampp/htdocs/local.example.com/public/www.example.com/www"
DirectoryIndex index.html index.htm index.shtml index.php
In the .htaccess I have:
RewriteCond %{REQUEST_URI} ^/$
RewriteCond %{SERVER_NAME} ^(.*)\.example\.com$ NC]
RewriteCond %{DOCUMENT_ROOT}/static/filecache/prerendered/%1/index.html -f
RewriteRule .* /static/filecache/prerendered/%1/index.html [L]
The file C:/xampp/htdocs/local.example.com/public/www.example.com/www/static/filecache/prerendered/local/index.html exists in the filesystem. This can be seen in the log too.
When I make a request to http://local.example.com/, the following comes up in the rewrite log:

I'm wondering why apache is initializing the rewrite engine with /index.html, /index.htm, /index.shtml and /index.php, even though an internal redirect happened earlier. Shouldn't it initialize the rewrite engine in the next loop with the new path (/static/filecache/prerendered/local/index.html)? The file exists but is not output by apache. According to http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule, the path /static/... should be handled as a file-system path relative to the document root:
file-system path Designates the location on the file-system of the resource to be delivered to the client. Substitutions are only treated as a file-system path when the rule is configured in server (virtualhost) context and the first component of the path in the substitution exists in the file-system URL-path A DocumentRoot-relative path to the resource to be served. Note that mod_rewrite tries to guess whether you have specified a file-system path or a URL-path by checking to see if the first segment of the path exists at the root of the file-system. For example, if you specify a Substitution string of /www/file.html, then this will be treated as a URL-path unless a directory named www exists at the root or your file-system (or, in the case of using rewrites in a .htaccess file, relative to your document root), in which case it will be treated as a file-system path. If you wish other URL-mapping directives (such as Alias) to be applied to the resulting URL-path, use the [PT] flag as described below.
I have looked at this Mod_Rewrite unexpected behavior L flag question and answer, but I dont think that my question is explained there. If it is, I seem to be missing something.
