How to log request inputstream with HttpModule, then reset InputStream position

Question

I am trying to log the contents of an http request, using an IHttpModule like so:

public class LoggingModule : IHttpModule
{
    public void Init(HttpApplica         


        

Answer 1

I've worked out the problem: I think that calling dispose on the StreamReader must be killing the InputStream too.

Instead of using the StreamReader I did the following:

        var bytes = new byte[request.InputStream.Length];
        request.InputStream.Read(bytes, 0, bytes.Length);
        request.InputStream.Position = 0;
        string content = Encoding.ASCII.GetString(bytes);

So the complete code:

public class LoggingModule : IHttpModule
{
    public void Init(HttpApplication context)
    {
        context.BeginRequest += ContextBeginRequest;
    }

    private void ContextBeginRequest(object sender, EventArgs e)
    {
        var request = ((HttpApplication)sender).Request;

        var bytes = new byte[request.InputStream.Length];
        request.InputStream.Read(bytes, 0, bytes.Length);
        request.InputStream.Position = 0;
        string content = Encoding.ASCII.GetString(bytes);

        LogRequest(content)
    }
}
