A common challenge facing all users within SharePoint is having an ability to update their site to a newer version of a template. The CorasWorks Application Designer Solution overcomes this by including a built-in Version upgrade feature.
To upgrade to a newer version, most users will access their Versions tab within the Options and choose a new option under the “Available Versions” section. When the changes are published the updated version is applied to the site. These changed files are copied via the CorasWorks Content Delivery Network (CDN), servers set up to serve supporting files for the Application Designer.
However, secure environments that do not have Internet access will run into a problem with this approach. Since they are blocked from the Internet they will not be able to access the CDN servers.
As major version updates are made to the CorasWorks Application Designer Solution v4, CorasWorks is expecting to be able to provide a package of the changes for installation onto the server. This will allow for the updating of the Application Designer’s content cache files on the server.
For secure environments, there is a web.config entry that is required to disable the checking for the CDN via the Application Designer. Look for the following line under appSettings:
<add key="UseAppDesignerCDN" value="true" />
If running in a secure location, change the “true” to false. That will prevent the system from trying to access the CDN servers.
