You know that you dont actually need to create a HttpModule right?

You can also read the contents of the Request.InputStream from within your asmx WebMethod.

Here is an article I wrote on this approach.

Code is as follows:

using System;
using System.Collections.Generic;
using System.Web;
using System.Xml;
using System.IO;
using System.Text;
using System.Web.Services;
using System.Web.Services.Protocols;

namespace SoapRequestEcho
{
  [WebService(
  Namespace = "http://soap.request.echo.com/",
  Name = "SoapRequestEcho")]
  public class EchoWebService : WebService
  {

    [WebMethod(Description = "Echo Soap Request")]
    public XmlDocument EchoSoapRequest(int input)
    {
      // Initialize soap request XML
      XmlDocument xmlSoapRequest = new XmlDocument();

      // Get raw request body
      Stream receiveStream = HttpContext.Current.Request.InputStream;

      // Move to beginning of input stream and read
      receiveStream.Position = 0;
      using (StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8))
      {
        // Load into XML document
        xmlSoapRequest.Load(readStream);
      }

      // Return
      return xmlSoapRequest;
    }
  }
}
