FarCry Tip - Enable cfc's in your Railo ProxyPassMatch

I ran into an issue today while working on a FarCry project, basically when I opened up the “Related Content” popup from the WYSIWYG editor it was blank. Nothing. Not the usual tabs for Images, File, Flash etc.

The Railo logs were empty but Apache was throwing a strange error which I hadn’t seen before: “Couldn’t initialize from remote server, JRun server(s) probably down.”. Funny as I’m not even using JRun!

Looking at the Chrome console I could see that opening the popup made a request directly to a cfc (/webtop/facade/tinyMCE.cfc?method=ajaxGetTemplateDropdowns) and returned the following error: “Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Eventually Mark pointed me in the right direction which was kind of obvious if I’d actually read the error properly! Our config for Apache -> Railo is for cfm’s only…not cfc’s. I don’t really like the approach of calling cfc’s directly at all, which is why it’s not in our Apache -> Railo proxy. But it wasn’t a big deal to add it for FarCry projects.

Here is the config we now use, note we now pass requests for cfm and cfc to Railo:

        <IfModule mod_proxy_ajp.c>
                <Proxy *>
                        Order deny,allow
                        Allow from all
                ProxyPassMatch ^/(.*\.cf[cm])$ ajp://$1
                ProxyPassReverse  /  ajp://

And of course now the related content popup works :)
