Content Delivery Network (CDN)

The web files for the eLauncher and Argos Web Viewer are now loaded on demand from Evisions’ servers. This allows us to deploy updates to the product launch page and Argos Web Viewer without requiring you to update the MAPS service or the Argos mapplet. Evisions uses a Content Delivery Network (CDN) to host the pages. The Content Delivery Network (CDN) URL field on the HTTP File Server screen contains the location where MAPS looks for the CDN:

The default URL points to the hosted content on Evisions’ servers, located at https://webapp01.evisions.com/. Altering this URL will cause MAPS to look in a different location for the eLauncher and Web Viewer files and should only be done when working with an Evisions tech to resolve a support issue.

If you do not wish to use the hosted files, you can continue to use the local versions included in the MAPS service and Argos mapplet by blanking out the CDN URL field (remove the URL entirely). In this case, you will need to wait for new releases of MAPS and Argos before you can get the latest updates to the eLauncher or Web Viewer.

When the CDN is enabled, if a user cannot access the CDN resources for some reason, MAPS serves up the local versions of the launch page and Web Viewer. This ensures seamless access in the event of a network outage or other issue that interferes with accessing the hosted content. You can check the version number at the bottom of the eLauncher or in the Help -> About in the Web Viewer to see which version of the software you are currently running, in case the local and hosted versions are different.

Note: In order to retrieve content from the CDN, end users must be able to access the CDN URL over the internet. If users are unable to access this location, MAPS will load the local version of the eLauncher and Argos Web Viewer.
