At our office, our security team has been running yum updates on our rhel5 servers. One of the affected packages is the httpd package. Before the update, we were successfully able to utilize mod_rewrite in apache to direct all traffic from accessing the directory alone to a file titled browse.php, but after the updates were run, the rewrite rules mysteriously stopped working. The version of httpd prior to the yum update was 2.2.3-45.el5, and after the update, it was 2.2.3-45.el5_6.1. The rewrite rule as displayed in the httpd.conf file reads (with substitutions of the directory and file names):

RewriteEngine on
RewriteRule ^/directory(?:/)?$ /directory/browse.php [R=permanent,L]

Now when we browse to the application via the URL http://example.com/directory, the page will not redirect, and will instead consume CPU until crashing the system (I've seen somewhere in the range of several dozen lingering processes), while going to the URL: http://example.com/directory/ (the difference being in the final /) will redirect the user to http://domain/directory/browse.php properly.

As tests, we are unable to replicate this on any other rhel5 servers. We've commented out the rewrite rules in the configuration, relying on an index.html file to handle the redirect in the <head> tag to no avail. I've enabled and reviewed the server-status page on apache, the processes are stuck on the reply stage, and they are not getting logged in any apache logs (error, access, nothing). I've moved the codebase into a separate directory and am able to redirect to it successfully without any rewrite rules when in another directory (relying on the aforementioned index.html file). I've recreated the problematic directory with a simple index.html file and it won't load. I've also been able to create an arbitrary directory in the document root for apache and placed a simple index.html file in it, which loads properly, it is only that specific directory that is proving problematic. We do sit behind a bluecoat proxy server, but I've eliminated that from the list of possibilities by replicating the issue when going directly to the server. We've rolled back the version of apache, and attempted to recreate this on other servers by doing partial updates to see if any specific package is causing it, unsuccessful in replicating the issue.

The following code is the contents of my httpd.conf file excluding the above rewrite lines:

The old server probably normalized the directory access before it reached your rewrite rule (I mean it added a slash after directory name if it wasn't there - it's normal behavior)

The cleanest would be to fix your conditional rule:

RewriteEngine on
RewriteRule ^/directory(/|)?$ /directory/browse.php [R=permanent,L]
