Persistent connections / https

I have an application which uses the multi interface. Within the application there are multiple requests being made to different servers, so it acts something similar to a browser. I need to be able to reuse connections to servers, especially in the case of https.

From sources on the internet, I have found that this should be made automatically as long as the curl easy handle is not cleaned up. And in the same way it’s also said that “just keep using the same easy handle”.

From the application perspective, since I have several requests to different servers and a layer handling all communication. Will I need to keep track of which easy handles are used for which server (and maybe also for which session)? That’s quite a lot of management code that’s needed if so… (It seems to me that each transfer is made on a separate handle, and when the transfer is finished the handle may be reused.)

Also, for the curl multi handle, basically the same question. The same multi handle can be used for different server request (simultaneously), I guess?

So as you can see, I’m a bit lost regarding the overall philosophy. I’d be thankful if someone could help me on the way.

As for my code, it’s working asynchronously with the Curl interface. That is, one thread that interfaces Curl, and serves all transfers towards the application.
