We have developed a web application and use XData and WebCore. Under Windows, Android the connection to the XData server works. In Safari we get the error message "Failed to load Resource"
any ideas
Sorry but this is a very vague description. Without knowing any detail about your application, what is happening, what exact functionality is used, I cannot really guess what could be going on here.
It doesn't make much sense that you get a error 503 from Safari but not from other servers. 503 means an error in the server. The XData server doesn't handle anything that is browser-specific.
Can I send a test URL to the support mail? The different behavior can be reproduced via this URL.
Yes, please contact support by email
