Note that despite my support for using http_async_query, I do agree with this point: If
queries are more than very occasional, I'd build a purpose driven kamailio instance
for handling a SIP to HTTP bridge.
HOWEVER given the original post context and code, it appears that this is their goal.
Given the number of services that are offered -ONLY- over http, the response of
"TL;DR don't do HTTP queries from Kamailio. Just don’t," can easily be taken
to mean "don't use kamailio, because it can't do HTTP request", which I
completely reject. Be smart, understand the intricacies of using it, but don't act
like it is a world killer.

Indeed, and this is what I do when I absolutely must use HTTP. We've built some
relatively performant SIP-to-HTTP data query bridges that way.
But when something is a poor fit, it's a poor fit. Kamailio is not a natural habitat
for HTTP queries.

YES! You've just summarised the central
thesis about async that I made in this blog post:

Well, you can set up a cluster of background workers and use the normal http_client. That
will speed up the process to read from the network as the network client processes are
freed up by you suspending the transaction and continuing in a background process (which
you need many of). This will make life better in some cases, but not all.
