How to detect server side exception when using remoting?
Can anyone provide any help?Thanks in advance.
when you send a request to the server you get an http return code. 200 and 304 means OK if another code returns it means you have problem with your serverside code. SSL has special Session Codes for this but http doesnt. You can return an error code and handle it with your js code.
