I am calling a RESTful web service in the back-end of some ASP.NET pages.

I am using ASP.NET asynchronous pages, so under the hood I am using the methods:

HttpWebRequest BeginGetResponse()

and

HttpWebRequest EndGetResponse()

The response string in my case is always a JSON string. I use the following code to read the entire string:

using (StreamReader sr = new StreamReader(myHttpWebResponse.GetResponseStream()))
{
  myObject.JSONData = sr.ReadToEnd();
}

Is this method OK in terms of scalability? I have seen other code samples that instead retrieve the response data in blocks using Read(). My primary goal is scalability, so this back-end call can be made across many concurrent page hits.

Thanks, Frank
