Web Farm Cache for 2sxc

Use 2sxc in multi-server environments using this farm-cache enhancement which will tie into the multi-server DNN Cache Management. So if you are using DNN in a multi-server environment and have all that set up, this will ensure that 2sxc also refreshes the caches across servers.

What it does

  1. Keep memory cache of the data (both 2sxc Content and 2sxc Apps) in sync
  2. Tell each server to refresh the cache whenever something is edited
  3. ...thereby keeping the servers and output in sync 

What does it not do

  1. File-Sync
    This you must ensure at server level. Typically WebFarms use a shared storage (NAS or SAN) or a third-party file-sync system. We suggest using a NAS/SAN.
  2. DNN Memory Sharing
    You must ensure this first. The 2sxc Web Farm Cache relies on this to work. This can be done done using any of the following:
    1. The free, open-source Redis Cache (requires a simple Redis-Server) - 2sxc has been tested with this
    2. nBrane WebFarm Cache
    3. DNN Professional (DNN Evoq) - 2sxc has been tested with this
    4. or using your own or another 3rd party DNN web farm cache

Please note that this is an enhancement for 2sxc, the free, open-source CMS / Dynamic-Content System for DNN. It won't do anything when used without 2sxc. 


Because this is an enterprise feature, we want to be sure that you're using it correctly. Here's what you must know:

  1. It's only supported for LTS (Long Term Support) versions of 2sxc
  2. You must have DNN configured to be multi-server - otherwise this feature won't do much for you. So you'll need the DNN-Caches to be in sync before adding the 2sxc-cache provider. This is default in Evoq-Setups, but needs a bit of work to run in standard DNN.  

Annual Subscription

You can purchase an annual subscription for 750.- per DNN server per Year. During this time you are entitled to using the latest releases (incl. new versions) for the duration of the agreement.

  1. Pricing covers software and installation support for the cache plugin for up to 3 months after purchase.
  2. Pricing also covers fixes / enhancements to this plugin, if it doesn't perform correctly within 3 months of purchase. This is very unlikely as it's being used on many live servers, but we've added this just so you feel good :)
  3. Further services will be charged separately.

The price does not include

  1. ...any support to setup Dnn Web Farm Cache - if you need help with this, we will quote this separately
  2. ...any support on 2sxc itself or on anything you build with 2sxc, like Razor, JavaScript, etc.

If an annual license is cancelled before automatic renewal, you may continue to use the last version released during the subscription. 

Licensing Examples

  1. If you have 1 windows server running any number of DNNs which don't share the cache, you don't need this - for a total of USD 0 😉
  2. if you have 2 DNN servers in a farm, you need 2 licenses for a total
    1. Annual recurring license of USD 1'500
  3. If you have 2 DNN servers in a farm running 58 portals, you still need 2 licenses (see above)
  4. If you have 6 Windows-Servers each running 3 DNN installations with 275 portals, then you need 1 license per DNN installation using the farm cache, in this case it would be 18 installations (6x3) for a total of
    1. Annual recurring license of USD 13'500
  5. If you have dev-servers running the farm cache, these too need to be licensed. Please keep in mind that it's a very fair price and that often the dev-environment actually needs more of our support - so this is only fair.
