CFML on Tomcat via Apache AJP Proxy, Redux
I often use Tomcat as my servlet container to power my CFML apps (works great for ColdFusion, Open BlueDragon and Railo!). I've been perfectly happy with the power and flexibility of using Apache HTTPD's mod_rewrite with an AJP proxy, as Sean Corfield has detailed. Then, after repeating a lot of rewrite rules in all of my virtual host definitions, I decided to merely place the following in my main Apache configuration file:
Allow from 127.0.0.1
</Proxy>
ProxyPreserveHost On
ProxyPassMatch ^/(.+\.cf[cm])(/.*)?$ ajp://localhost:8009/$1$2
That's it! Now, any Apache virtual hosts for CFML application can be defined as simple as this:
ServerName myrockinapp
DocumentRoot /var/www/myrockinapp
DirectoryIndex index.cfm
</VirtualHost>
I can still easily add URL rewriting to my Apache virtual hosts. For example, when using Mura CMS I often set the properties siteIdInURLs=0 and indexFileInURLs=0 to make super clean looking URLs (with no siteID or index.cfm in the URLs). This then of course requires a rewrite rule to ensure the proper requests are passed to Tomcat, which is as simple as adding these lines to your virtual host (or an .htaccess file in your Web root):
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^([a-zA-Z0-9/-]+)$ /index.cfm%{REQUEST_URI} [PT]
Makes all the configuration I used in this post look a bit silly now :P
Also, if you're interested in a clean, production-worthy server setup running on Ubuntu 10.04 with Railo, Tomcat, Apache and MySQL, I have this fairly well documented in this Google Doc.

Thanks!

@Todd: Glad to help! I like me some clean config files too ;-)
I get an internal error using the above in an .htaccess (in the vhost webroot)
I think im nearly there. I have settings.ini.cfm set as siteidinurls=0 AND indexfileinurls=0.
Would the above work for Resin?
(end result im wanting is no siteid or index.cfm in the middle of the URL)
Cheers Sam
I'm glad you figured it out, but yes, probably worth mentioning that these apache mods need be enabled: proxy, proxy_ajp (or proxy_http) and rewrite. In Ubuntu/Debian that's as simple as:
sudo a2enmod proxy_ajp rewrite
sudo service apache2 restart
Thank you for generously contributing such a useful blog ... with code that works!
I came across this code, which greatly simplifies the https redirection, but how would I incorporate it with your solution?
RewriteCond %{SERVER_PORT}s ^(443(s)|[0-9]+s)$
RewriteRule ^(.+)$ - [env=askapache:%2]
# redirect urls with index.html to folder
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*index\.html\ HTTP/
RewriteRule ^(([^/]+/)*)index\.html$ http%{ENV:askapache}://%{HTTP_HOST}/$1 [R=301,L]
I'm definitely a novice with the mod_rewrite.
Thanks,
RewriteCond %{SERVER_PORT}s ^(443(s)|[0-9]+s)$
RewriteRule ^(.+)$ - [env=askapache:%2]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^([a-zA-Z0-9/-]+)$ http%{ENV:askapache}://%{SERVER_NAME}/index.cfm%{REQUEST_URI} [QSA,L]
After this processes, what can I do to remove the index.cfm?
I tried setting the [OSA,L] to [PT] then added:
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^([a-zA-Z0-9/-]+)$ http%{ENV:askapache}://%{SERVER_NAME}/index.cfm%{REQUEST_URI} [QSA,L]
No Luck... Any help would be greatly appreciated...
Sorry, I'm not sure exactly what your goal is here. Can you elaborate on what you're trying to accomplish?
FWIW, here's a sample Apache vhost pair (SSL and non-SSL) that works fine for me, with Railo running in Tomcat, and using the basic proxy config in Apache as described above in this post...
<VirtualHost *:80>
ServerName me.ssl
DocumentRoot /home/jkrug/www/ssl/www
DirectoryIndex index.cfm
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^([a-zA-Z0-9/-]+)$ /index.cfm%{REQUEST_URI} [PT]
</VirtualHost>
<VirtualHost *:443>
ServerName me.ssl
DocumentRoot /home/jkrug/www/ssl/www
DirectoryIndex index.cfm
SSLEngine on
SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
<FilesMatch "\.(cfc|cfm)$">
SSLOptions +StdEnvVars
</FilesMatch>
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^([a-zA-Z0-9/-]+)$ /index.cfm%{REQUEST_URI} [PT]
</VirtualHost>
Specifically, I have a URL "www.xyzcompany.com/support.faq"; and I get a 404 error from Apache stating the URL is not found on the server. If I change it to "www.xyzcompany.com/index.cfm/support.faq"; it works properly and the page is loaded.
I am not very familiar with mod_rewrite (I should be though) so I think there is a minor tweak needed to the pattern matching to accept URI values with a "." delimiter, right? The problem is I am not too sure how to go about this. Here is an example of a few rewrite rules I used to use in my vhost.conf file which allowed for URI values containing ".":
# If it's a CFML (*.cfc or *.cfm) request, just proxy it to Tomcat:
RewriteRule ^(.+\.cf[cm])(/.*)?$ ajp://%{HTTP_HOST}:8009$1$2 [P]
# If trailing slash and real directory, then append index.cfm and proxy it to Tomcat/OpenBlueDragon:
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^(.+/)$ ajp://%{HTTP_HOST}:8009%{REQUEST_URI}index.cfm [P]
# If it's a real file (and we haven't proxied to Tomcat, so it must be static), just serve it:
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f
RewriteRule . - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ([a-z]{1}.*)?$ ajp://%{HTTP_HOST}:8009/index.cfm/$1 [QSA,P]
Any thoughts on how to get your simplified mod_rewrite rules to accommodate "." delimited URI values?
To allow a period in your path info, you just need to add that character (escaped) to the regex. So, just add "\." before the hyphen:
RewriteRule ^([a-zA-Z0-9/\.-]+)$ /index.cfm%{REQUEST_URI} [PT]
HTH!
Been working the past week or two with your Google doc Ubuntu 10.x/ Tomcat6 / Railo setup on EC2 and so far so good. Wanted to note one piece I ended up adding as most of my Railo access is going over the flashservices/gateway.
After trying a few ways to resolve access to the gateway when connecting via a virtual host or virtual host alias, the solution ended up being the addition of the following to the httpd.conf:
ProxyPassMatch ^/flashservices/gateway(/.*)?$ ajp://localhost:8009/flashservices/gateway/$1$2
So far this seems to work as expected - connections to the flash gateways work and the cfc service paths are particular to the vhost. But my RegEx chops are pretty weak and I just did trial and errorred this based off your examples. Would definitely like to know what your thoughts are on it.
Thanks again for the excellent Google Doc, looking like I am going to end up with just about the setup I had hoped for.
Best,
J
