You can’t always save the client
“When you can do nothing, what can you do?”
As I’ve mentioned, you’re hired to be a consultant because you’re a problem-solver, so it really hurts when you can’t help a client. It’s a tough lesson, but it’s an important one:
Despite your best efforts,
you can’t always save the client.

If you ever need some good ScalaJ-HTTP examples, see the test files in the project, including this HttpBinTest.scala file. That file currently shows a number of good ScalaJ-HTTP examples, including GET, POST, redirect examples with Scala.
See that page for a full list of examples, but for my own use, here are a few of them.

Processing HTTP response headers with a ScalaJ-HTTP web client
By Alvin Alexander. Last updated: December 18 2018
If for some reason you ever want to print out some HTTP response headers from a HEAD request when using ScalaJ-HTTP as an HTTP client, this example may help point you in the right direction:
import scalaj.http._
object TestHead extends App
{
val response: HttpResponse[String] = Http("http://www.google.com")
.method("HEAD")
.timeout(connTimeoutMs = 2000, readTimeoutMs = 5000)
.asString
for ((k,v) <- response.headers) println(s"key: $k\nvalue: $v\n")
}
I may write more about ScalaJ-HTTP in the future, but for today that’s a quick example of processing the response headers/parameters when making a HEAD request.
