I said it, neither because it can't be done, nor because it is
incompatible with session caching, or has anything to do with
ephemeral key agreement (which works just fine even with
session resumption), but simply because it is easier for a
beginner to get the code working without SSL handle re-use.
Once you have you everything else working, and have become
more adept with use of the library, you can add connection
handle re-use and measure the performance impact. If it
makes a significant difference, then invest in maintaining
slightly more complex code to get the advantage.
That's all I can offer in light of the bellicose rant, ... :-(
