server-sent event on XS

Hi,

I am doing a POC of server-sent event on HANA XS (SPS06).

However I could not get it to work - after the first response is returned to client successfully, error is thrown from server side. Client side JS would then retry and fail and so on, effectively turning into polling.

I would like to know if HANA XS is capable of supporting server-sent event. Or does it do something like terminating the HTTP connection once response is written?

Thanks.

Regards,

Bin
