As of next week, all http requests to the MPG/SFX link resolver will be redirected to a corresponding https request.
The Max Planck Society electronic Book Index is scheduled to be switched to https only access the week after, starting on November 27, 2017.
Regular web browser use of the above services should not be affected.
Please thoroughly test any solutions that integrate these services via their web APIs.
Please consider re-subscribing to MPG.eBooks RSS feeds.
The MPG/SFX link resolver is now alternatively accessible via the https protocol. The secure base URL of the productive MPG/SFX instance is: https://sfx.mpg.de/sfx_local.
HTTPS support enables secure third-party sites to load or to embed content from MPG/SFX without causing mixed content errors. Please feel free to update your applications or your links to the MPG/SFX server.
The MPG Resource Navigator MPG.ReNa is now accessible via https only.
If in doubt, please double-check any routines and applications loading or embedding content via MPG.ReNa APIs.
Please note that you may need to re-subscribe to resource feeds, or update URLs of RSS widgets in your Content Management System, etc.
We apologize for any inconvenience.
