[Bug 56434] New: Rewrite rule for root / matches, but end flag is
ignored (subreq for index files still proceeds)
https://issues.apache.org/bugzilla/show_bug.cgi?id=56434
Bug ID: 56434
Summary: Rewrite rule for root / matches, but end flag is
ignored (subreq for index files still proceeds)
Product: Apache httpd-2
Version: 2.4.7
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: mod_rewrite
Assignee: bugs@httpd.apache.org
Reporter: normadize@gmail.com
As first asked on http://bit.ly/1hYKkHC and http://bit.ly/1hYKtL9
Apache 2.4.7 on Ubuntu 14.04. The rewrite rule is simple:
RewriteCond %{REQUEST_URI} ^/?$
RewriteRule ^ /web/wp-content/cache/page_enhanced/HOSTNAME/_index.html [L]
Basically, I want to serve an .html file for /. The .html file exists and is
served fine if requested directly. As you can see in the debug logs below the
cond on / does match (initial), but then Apache proceeds (subreq) and tries to
match /index.html, /index.cgi, /index.pl and /index.php, and finally serves
/index.php.
This is not expected since [L] should prevent Apache from continuing once a
match is found.
I can confirm that this problem does not exist in Apache 2.2.
Also, this appears to be a problem only for /. The same rule but for a
subdirectory works as expected, i.e.:
RewriteCond %{REQUEST_URI} ^/subdir/?$
RewriteRule ^ /web/wp-content/cache/page_enhanced/HOSTNAME/subdir/_index.html
[L]
... works just fine.
Rewrite debug logs:

mod_dir is looking for DirectoryIndex'es. There is a fix to the interaction
between the two mods in 2.4.9, can you confirm it fixes your problem?
*) mod_dir: Don't search for a DirectoryIndex or DirectorySlash on a URL
that was just rewritten by mod_rewrite. PR53929. [Eric Covener]

I just tried 2.4.9 and indeed the reported problem is gone. If any Ubuntu users
read this, there is a fairly actively maintained PPA at
https://launchpad.net/~ondrej/+archive/apache2 which works fine in Trusty, so
no need to compile.
