Found a solution !
Wrote custom Filter for attaching to Response objects Filter property:
1 public class ResponseFilterStream : Stream
2 {
3 private Stream stream;
4 private StreamWriter streamWriter;
5
6 public ResponseFilterStream(Stream stm)
7 {
8 stream = stm;
9 //streamWriter = new StreamWriter(stream, Encoding.UTF8);
10 streamWriter = new StreamWriter(stream);
11 }
12
13 public override void Write(byte[] buffer, int offset, int count)
14 {
15 MemoryStream ms = new MemoryStream(buffer, offset, count, false);
16 //StreamReader sr = new StreamReader(ms, Encoding.UTF8);
17 StreamReader sr = new StreamReader(ms);
18 string s;
19
20 while ((s = sr.ReadLine()) != null)
21 {
22 //s = s.Trim();
23
24 if (s != "")
25 {
26 if (s.StartsWith("<?xml version"))
27 {
28 streamWriter.Write("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
29 }
30 else
31 {
32 streamWriter.Write(s);
33 }
34 streamWriter.WriteLine();
35 }
36 }
37 streamWriter.Flush();
38 }
39
40 #region Rest of Stream's function - our stream is write-only
41
42 public override int Read(byte[] buffer, int offset, int count)
43 {
44 throw new NotSupportedException();
45 }
46
47 public override bool CanRead
48 {
49 get { return false; }
50 }
51
52 public override bool CanSeek
53 {
54 get { return false; }
55 }
56
57 public override bool CanWrite
58 {
59 get { return true; }
60 }
61
62 public override long Length
63 {
64 get { throw new NotSupportedException(); }
65 }
66
67 public override long Position
68 {
69 get { throw new NotSupportedException(); }
70 set { throw new NotSupportedException(); }
71 }
72
73 public override void Flush()
74 {
75 stream.Flush();
76 }
77
78 public override long Seek(long offset, SeekOrigin origin)
79 {
80 throw new NotSupportedException();
81 }
82
83 public override void SetLength(long value)
84 {
85 throw new NotSupportedException();
86 }
87
88 #endregion
89 }
Attached newly created Filter in Global.asax
1 protected void Application_PostRequestHandlerExecute(object sender, EventArgs e)
2 {
3 if (Response.ContentType == "text/vnd.wap.wml")
4 Response.Filter = new ResponseFilterStream(Response.Filter);
5 }
