Revproxy is working quite well for a variety of requests now.
One more issue we are encountering while spooling responses back to the
client, is a fairly sizeable delay before the connection is being closed.
This happens when the proxy is proxying to another port on localhost (which
is how we run our development environments). I couldn't reproduce when
upstream was a different server.
For example, requesting a single file, the revproxy code very quickly
receives the reply from upstream, then the spool callback proceeds to
return the result to client in 4096 chunks.
These happen rapidly until the final chunk. In that case, we get a ~5
second delay, then finally the last spool callback is triggered, the final
chunk of data is sent, then the connection is auto closed by the spool proc.
In the following log extract the delay can be seen between 18:25:52 &
18:25:57

This was a quick test case based on the latest code:
Naviserver Config
<https://gist.github.com/davidqc/980ace1188f0537f3d616b847ccc2f3b>
Naviserver Init
<https://gist.github.com/davidqc/0f0d5210fa16012f35afec4fde5f86c9>
Add a static file to pages/, then https://www.test.co.uk/proxy/file.html
The content is displayed but the connection does not close for > 5 seconds.
Any ideas why this might be happening?
I'll continue to try to narrow it down...
Regards,
David
