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
EEM 8.4, 12.x
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.
This error can be safely ignored, does not affect the functionality of igateway and its modules.
