http request params problem

Hi all,

I have following strange problem - I want to send data to server via HTTP:POST method. Here is my code:

iSocketServ.Connect();
iConnection.Open(iSocketServ);
   
_LIT8(KContentType, "text/html");

RStringPool string_pool = iHttpSession.StringPool();
RStringF method = string_pool.StringF(HTTP::EPOST, RHTTPSession::GetTable());

TUriParser8 uri;
uri.Parse(*request);   

iTransaction = iHttpSession.OpenTransactionL(uri, *this, method);
   
RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection();
RStringF cont_type_str = string_pool.OpenFStringL(KContentType);
THTTPHdrVal cont_type(cont_type_str);
hdr.SetFieldL(string_pool.StringF(HTTP::EContentType,RHTTPSession::GetTable()), cont_type);
cont_type_str.Close();   

iTransaction.Request().SetBody(*this);
iTransaction.SubmitL();

When my url is:
http://123.123.123.123/application/page.aspx - connection to sever is ok

but when url is : http://123.123.123.123/application/page.aspx?data=123*value;2;value1*

the THTTPEvent status  in my MHFRunL is EFailed

thanks!
