As per my understanding aspx is the page and the .ashx is the code file which response back the output, in string format and .ashx file is a web handler. A web handler file works just like an aspx file....

So we consider.ashx same as .aspx then this code should work for you(which is running for me for .aspx page). This is making request to .net server.

iOS

    UIImage *img = [UIImage imageNamed:@"test.png"];
    NSData *imageData = UIImageJPEGRepresentation ( img , 90 );

    NSString *urlString =@"www.xyz.com/ImageUpload.aspx?filename=test";

    NSLog(@"IMAGE_UPLOAD_URL -------------> %@",urlString);

    NSMutableURLRequest *request = [[[ NSMutableURLRequest alloc ] init ] autorelease ];
    [request setURL :[ NSURL URLWithString :urlString]];
    [request setHTTPMethod : @"POST" ];
    NSString *boundary = @"---------------------------14737809831466499882746641449";
    NSString *contentType = [ NSString stringWithFormat : @"multipart/form-data; boundary=%@" ,boundary];
    [request addValue :contentType forHTTPHeaderField : @"Content-Type" ];
    /*  body of the post */
    NSMutableData *body = [ NSMutableData data ];
    [body appendData :[ NSData dataWithData :imageData]];
    [request setHTTPBody :body];
    NSData *returnData = [ NSURLConnection sendSynchronousRequest :request returningResponse : nil error : nil ];

    NSString *returnString = [[ NSString alloc ] initWithData :returnData encoding : NSUTF8StringEncoding ];
    InfoLog(@"_______  IMAGE_UPLOAD response -------------> .%@.",returnString);

.NET

Retrieving image like this for .aspx page 

    if (Request.QueryString["filename"] != null)
    {
        string filename = Request.QueryString["filename"].ToString();
        string saveFilePath = ConfigurationManager.AppSettings["CPSBImageFolder"].ToString();
        //string saveFilePath = Server.MapPath("~/images");
        saveFilePath = saveFilePath + filename;
        Stream objStream = Request.InputStream;
        StreamReader objStreamReader = new StreamReader(objStream);
        Image image = Image.FromStream(objStreamReader.BaseStream, true);
        ImageCodecInfo[] info = ImageCodecInfo.GetImageEncoders();
        EncoderParameters param = new EncoderParameters(1);
        param.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);
        image.Save(saveFilePath, info[1], param);
        Response.Write("true");
    }

Not sure but hope this give you a clue.

Verify that the variable(NSData) you are using to upload image is not null & your dot net server is receiving request.
