[Mono-list] Request.InputStream exception

[Peter]

Hello,

I figured out what was wrong. If the Http request has no content then trying to access the Request.Inputstream fails. So the following code works:

...

public void ProcessRequest(HttpContext context) 
{ 
        try 
        {
		string _request = string.Empty;
		if (this._context.Request.ContentLength>0)
		{ 
                	StreamReader _streamReader = new StreamReader(context.Request.InputStream); 
                	_request = _streamReader.ReadToEnd();
		}

                this._context = context; 
                this.RequestRouter(); 
        } 
        catch 
        { 
                throw; 
        } 
}

...

The IF..THEN is not neccessary in .Net 1.1.

Regards,

Peter
