MSXML2.ServerXM LHTTP to HttpWebRequest: Error 500

[Maris Janis Vasilevskis]

Hi,

Is it possible to force HttpWebRequest to do exactly (not approximately) the same as MSXML2.ServerXM LHTTP does?

More details. I port JScript to JScript.NET

I have a server (ASP invoking binary code; code not accessible).
I send XML requests to it.
If my request is accepted, ServerXMLHTTP returns XML with accept details.
If my request is rejected, ServerXMLHTTP returns XML with reject details.
ServerXMLHTTP always returns XML.

For accepted requests, HttpWebRequest returns the same as ServerXMLHTTP.
But for rejected requests, HttpWebRequest fails with (500) Internal Server Error.

My JScript:
function GetResponse(xml text) {
var xmlhttp, res;
xmlhttp = new ActiveXObject(" MSXML2.ServerXM LHTTP");
xmlhttp.open( "POST", MyUrl, false );
xmlhttp.setRequ estHeader( "Content-Type", "text/xml" );
xmlhttp.send( xmltext );
res = xmlhttp.respons eText;
xmlhttp = null;
return res;
}

My JScript.NET:
static public function GetResponse(xml text:String):St ring {
var req:HttpWebRequ est;
var rsp:HttpWebResp onse;
var wr:StreamWriter ;
var rd:StreamReader ;
var res:String;
req=HttpWebRequ est(WebRequest. Create(MyUrl));
req.Method='POS T';
req.ContentType ='text/xml';
wr=new StreamWriter(re q.GetRequestStr eam());
try { wr.Write(xmltex t); } finally { wr.Close(); }
rsp = HttpWebResponse (req.GetRespons e()); // Possible Exception 500 here !!
rd=new StreamReader(rs p.GetResponseSt ream());
res=rd.ReadToEn d();
rd.Close();
return res;
}
I played also with Credentials, ContentLength and StreamWriter Encoding, without success.

Thank you,
Mahris

Hold on, if the request is rejected - what do you want to happen?

It doesn't sound unreasonable to have code to handle errors that may be
coming back from the server.

Thank you, Marina.
However, I cannot hold on, I need to analyze the reject message.

But I found the reason.
In the server trace I see that 500 is generated for both, ServerXMLHTTP and HttpWebRequest,
together with a good XML.
Simply, ServerXMLHTTP returns the result but HttpWebRequest throws error.

So, my current solution:
static public function GetResponse(xml text:String):St ring {
var req:HttpWebRequ est;
var rsp:HttpWebResp onse;
var wr:StreamWriter ;
var rd:StreamReader ;
var res:String;
req=HttpWebRequ est(WebRequest. Create(cst.Soap URL));
req.Method='POS T';
req.ContentType ='text/xml';
wr=new StreamWriter(re q.GetRequestStr eam());
try { wr.Write(xmltex t); } finally { wr.Close(); }
try {
rsp = HttpWebResponse (req.GetRespons e());
}
catch(e:System. Net.WebExceptio n) {
if(e.Status==Sy stem.Net.WebExc eptionStatus.Pr otocolError) {
rsp = HttpWebResponse (e.Response);
}
else throw e;
}
rd=new StreamReader(rs p.GetResponseSt ream());
res=rd.ReadToEn d();
rd.Close();
return res;
}
