SSE:Server Sent Events

[polymath-in]

I want to write server sent event handler. How can I use lack for that? Is it possible to use delayed response for that? I am a newbie.

Sup @polymath-in.
So SSE is an HTTP/2 server addition.
Lack is not an HTTP server. Under-lying lack is clack, a server agnostic cradle that handles the lower-level details of the actual server which is still one level lower.
The servers available are :woo :hunchentoot :toot and some more I think.
At the lowest level the HTTP protocol will be decided and used.
The standard protocol used is HTTP/1.1 with clack/lack and the server chosen under that, and I am not aware of any production servers in CL that could be used with clack/lack for HTTP/2.
Clack/lack cannot handle HTTP/2 server protocol.

I hope that clears up the confusion a bit, and I trust your journey through learning the technical details are turning out fruitful.

Please close this issue. Cheers
