XML API calls are case sensitive for custom applications

Problem Statement: Any custom application, using XML API’s for sending out requests may return an error due to case sensitive characters.

Environment:

• Adobe Connect hosted
• Adobe Connect on-premise
• Connect version 9.8

This issue happens due to follow:
(WARN) InvalidDomain error while accessing host=eCON****.adobeconnect.com admin-host=na*cps.adobeconnect.com host-name=pacna*app** account-domain=econ****.adobeconnect.com
Note: The request sent out to a URL which includes upper case in the domain name.

Reason for this behavior:
There was recently additional security protection applied on the server on verifying if the URL used matches with the account’s domain.

Solution:
As long as API’s are running on 9.8, URL should always have lowercase letters in the domain name.

Additional Information:

• Using web browsers we cannot verify this behavior, since by default domain changes to lowercase letters, before making the API call.
  
• There is Bug# CONN-4107331 logged and the fix is 9.8.1_sustaining.
