hunchentoot serving manifest files, ie. .appcache files.

[Hans Hübner]

While SSE wins over WebSockets in terms of simplicity, it should be noted
that intermediate http proxies may not deal with the protocol in the
required ways (i.e. the proxy may not forward the request until the whole
response has been read).  One way around that is to use https, which will
implicitly make the proxy forward the connection directly to the origin
server, but may be forbidden by some proxies altogether.  WebSockets share
the problem, but as they are defined a bit more strictly than SSE, they may
see more support in intermediate proxies.

The only universally safe way to push events from a HTTP server to a client
is to use (long) polling.  Other methods are not advisable if universal
availability of the service is desired.

It is unfortunate that there is no maintained WebSockets service that works
well with Hunchentoot.  There once was Hunchensocket, but it did not
receive any love over the last few years and thus requires considerable
work to bring it up to date.
