### Example
let unreachableProxy = "http://127.0.0.1:8888"
try:
  let client = newHttpClient(proxy=newProxy(unreachableProxy), timeout=1)
  var res = client.getContent("https://github.com")
  echo res
except:
  echo "Timed out"

Current Output

timeout variable is ignored, program stuck until default socket timeout will happen

Expected Output
