[SR-Users] Does http_client module block the execution of the kamailio thread?

[Alex Balashov]

Yes, it does. And, although, there are plenty of ways to use it “asynchronously” without using http_async_client (e.g. mqueue and rtimer, or the async module wrappers), you’ll find that http_async_client, viewed in that light, doesn’t seem so complicated after all.

My plan is to use it to get some information from my system, and so it will be called for every INVITE request, and I'm afraid of the performance considerations.
