Not sure why you agressivly attack me.
But sorry. This was more than a decade ago, I've done dozens and dozens of projects since then with Java, C, Ruby, Python, Clojure, Scala, Javascript, Coffescript and Typescript and more, so I can't remember 'exactly' what libaries I was using more than 10 years ago in some Perl projects.
"Now you're addressing completely different"
I beg to differ, in my book credit card processing during e-commerce checkou and accessing backend services with HTTP are in the problem domain of 'web development', but it might be different for your 'web applications'.
