Question

I am looking for a http client in scala, that handles redirects. How do I fetch the content of a Url in scala, handling redirects?

I saw the scala.io.Source examples, but they dont handle redirects.

If you don’t want to use something like HttpClient (which is probably better for anything beyond toy examples), you can tinker with the URLConnection:

def urlToStream(url: String) = Source.fromInputStream(
  (new java.net.URL(url).openConnection match {
    case connection: java.net.HttpURLConnection => {
      connection.setInstanceFollowRedirects(true)
      connection
    }
    case connection => connection
  }).getInputStream
)

This will turn on redirect following if the protocol is HTTP.
