(Ruby) Cancel HTTP Get Async Task if not Completed after a Max Time

Demonstrates how to wait a maximum amount of time for an asynchronous task to completed. If not completed in the allotted amount of time, the task is cancelled.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

# Set some timeouts, in seconds:
http.put_ConnectTimeout(15)
# ReadTimeout specifies the max number of seconds that must elapse when no additional data is received before
# timing out.  For example, if a server sends a 300 byte response at the rate of 1 byte per second, then
# ReadTimeout would never cause a timeout because there is never a 15 second interval when nothing arrives.
http.put_ReadTimeout(15)

url = "https://your-url.com/something"
# task is a CkTask
task = http.QuickGetStrAsync(url)
task.Run()

# Wait a maximum of waitMaxMs for the task (i.e. the HTTP GET) to complete.
# The Wait method returns when the task has been canceled, aborted, or completed, or when the max allotted time has passed.
waitMaxMs = 20000
task.Wait(waitMaxMs)

# At this point, the GET may or may not have completed.  
# Rather than checking the Task status, we can call task.Cancel because
# if the Task is no longer running (because it already completed, was canceled or aborted), then the 
# call to Cancel is a NO-OP (meaning it does nothing and the Task's status is unaffected).
# Also, task.Cancel returns true if the task was in the "queued" or "running" state and was canceled or aborted. 
# The method returns false if the task has any other status.
wasCanceled = task.Cancel()
if (wasCanceled == true)
    print "The HTTP GET took too long and was canceled." + "\n";
else
    # Find out what happened.
    if (task.get_StatusInt() == 7)
        # The task completed, which means the background thread's call to QuickGetStr completed
        # with success or failure.  Find out which...
        if (task.get_TaskSuccess() == true)
            # Get the string response for the call to QuickGetStr (which happened in Chilkat's background thread).
            responseStr = task.getResultString()
            print responseStr + "\n";
            print "HTTP GET successful!" + "\n";

            print "HTTP GET failed prior to waitMaxMs..." + "\n";

        # The task must've been canceled or aborted by some other means..
