Symptoms
In EEM environments, the igateway.log captures the below ERROR message.
ERROR :: SponsorManager::submit :sponsor[ favicon.ico] not found and invocation returned 404 error , logged to igateway.log
Environment:
EEM 8.4, 12.x
Cause:
The reason is that all the browsers try to get favicon.ico file, if it is not provided with the homepage. This image file is used to display favicon and bookmark/website icon. Since we don't provide favicon.ico file with iTech, browsers sent a request on their own to get this file in the root directory of the Web Server. So in this case, the GET request used to go in format " http://:5250/favicon.ico". Since igateway cannot understand this format, it throws the sponsor not found error and ignores it.
Resolution:
This error can be safely ignored, does not affect the functionality of igateway and its modules.
