Processing HTTP response headers with a ScalaJ-HTTP web client

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.
