HttpWebRequest Accept-Encoding: gzip Header

Hi,
I've developed a solution to call a webservice via HTTPWebRequest
The IIS is configured to allow compression (gzip).
The client application add to the request header the accept-
encoding:gzip
request.AllowWriteStreamBuffering = true;
request.SendChunked = false;
request.KeepAlive = true;
request.Method = "POST";
// tell the HTTP server that the client accept compressed
data
request.Headers.Add("Accept-Encoding: gzipr\n");
I've tested with success the code on my laptop, but on my pocket Pc
this does not work. I mean, i can successfully call the webservice but
i never receive the contents compressed.
In order to demystify this issue I've placed an http sniffer and came
to the conclusion that when i run the code into my laptop the header
accept-encoding is sent and from Pocket PC is not (this way the IIS
cant know if the client allows compression).
Investigating a little more i did the following:
request.Headers.Add("Accept-Encoding: gzipr\n");
request.Headers.Add("TestHeader: okr\n");
Running this code in pocket PC i saw that he sends the "TestHeader"
Header. He only omits the Accept-Encoding. Why is that?
Note: This behaviour occurs on Compact Framework 1.1 and 2.0; on
pocket pc 2003 mobile edition and on WinCE 5.0
What is happening? Can you help me?
Thanx
.
