Re: [Cppcms-users] Server Sent events and CppCMS

[Artyom B. <art...@ya...>]

I had changed your example a little:

1. Remove context from the list such that it would not write some more data
   until completion handler returns.
2. You use incorrectly completion handler - you need to receive the status
   in handler.
3. Reduced reconnect option so the client would reconnect immediatly


Also it would be better to use Last-Event-ID header and setup ids so the
client that is disconnected can reconnect and restart from correct point.

Small notes about streaming and flushing:

- In CppCMS internal server works 100%,
- In Lighttpd works 100%
- In Apache - it is required to add -flush option
- In nginx:
-- scgi it is required to add scgi_buffer off; option
-- fastcgi ... It is not possible to disable buffering - at least I 

   had not found one

   Once agains... STUPID nginx






Best,
