In the first part of the cache blog entry we looked at how we can use the cache directly without entering into great detail. Now let's have a look at what the cache is at capable of. Because it provides much more than just storing data.
It is long overdue, but a tutorial on how to create your own Railo extension provider is now available on the wiki. Why would you ever want to build your own extension provider? Perhaps you are a framework developer and you want to provide your users running Railo a 'one-click' installation / update. Perhaps you are managing several Railo servers and you want your internal servers to update to your the latest application / custom cfc / built-in-tags/functions, etc.
If you're unfamiliar with what Railo extensions are, they're essentially plug-ins that are available via the Railo team or with the help of the tutorial, you can create your own. If you want to see Railo extensions in action, you can log into your own web context ( http://{YOUR SERVER}/railo-context/admin/web.cfm?action=extension.applications ) and Railo will instantly download and install the many available frameworks (ColdBox, Fusebox, Model Glue, ColdSpring, Mach II, cfwheels, etc.) and applications ( Farcry, Mura, Galleon, Mangoblog, etc).
The Railo team also offers paid extensions (Amazon S3, cluster scope, admin sync, cfvideo and more) via the server context ( http://{YOUR SERVER}/railo-context/admin/server.cfm?action=extension.applications ).
Gert just tweeted about the "Ram Resource Info" being available on the preview site ( http://preview.getrailo.org/ExtensionProvider.cfc ). I thought I'd take a moment to show you how to install and use it.
I have just uploaded Andrea Campolonghi's current RC version of the ajax built in tags. Here's what you need to do in order to install and test the tags.
Even for myself this was absolutely stunning. I decided to write a series of tips for Railo and by doing this I stumbled across a problem Andrea Campolonghi had, who writes the Railo AJAX tag extensions we will include very soon. The problem was or is that he needed to read the content of a zip file that is inside another zip archive. Now how to do that without unzipping it into a local folder.
This is something we wanted to do for more than a year now. We wanted to implement a cache that is reachable from all the servers in a cluster. So here we go...
