aspx thread: SV: Re: The system.web namespace - quick one!


Message #1 by Anders Lundholm <alu@m...> on Wed, 8 Nov 2000 10:58:54 +0100
Hello Frederik (and thanks for the quick reply).



I'm aware that the previous 'intrinsic' asp objects such as Server, 

Request

and Response are available through the context object (to make the life

easier for the aspx developers, I recon). However, I asked the question

because from the documentation, I couldn't actually see how to get the

objects

> HttpServerUtility(class System.Web.HttpContext context)



I didn't see that from the documentation. Is this because it's still in

pre-beta or what? I thought they'd described the class parameters 

properly

in the docs. Let me take a snip from the HttpServerUtility Class docs.



Object

 HttpServerUtility

  public class HttpServerUtility



This tells me it's not protected, but a public class ready to 

instantiate.

Isn't this correct?

> <%

> Server.Execute("connection.aspx");

Well, it doesn't work (perhaps because it only expects .aspx pages - 

lets

hope the next beta will support that). It works for .aspx pages but not 

for

.asp which is a big problem for me, as I'm building a big oo content

management system (yes, on a beta framework - clever). I'd like to 

offer the

.net un-enlightened people access to normal scripting blocks on the 

page. I

see no other way to do this but to use the server.execute method.



Any idea to the solution of executing regular asp scripting blocks 

without

using the server.execute method? =3D)



<sorry>

So many questions ..

</sorry>

Yes this is right.

I think MS have hide this from the class. Becuase if you use the class 

viewer it will not display the HttpSystemUtility constructor.

But if you open System.Web.dll file in ILdasm.exe you will se it.



The HTTPSystemUtitlity class is public but It look like we can't use 

the HTTPContext with HTTPSystemUtitlity.

I think this is done that way, because of we should not do something 

that can hang the context. I will take a deeper look at this.

I think this is becuase the Server.Execute will runt the file you pass 

with the .Net runtime engine and it doesn't support .asp

hmm, Maybe you can use the WebRequestFactory classe in the system.net 

namespace to execute a .asp page.



Here is an example how you can use the WebRequestFactory.



<%@ Page language="C#"  %>

<%@ Assembly Name="System.Net.dll" %>

<%@ Import Namespace="System.Net" %>

<%@ Import Namespace="System.IO" %>

<SCRIPT runat="server" LANGUAGE="C#">



	public void Page_Load( Object s, EventArgs E )

	{

		WebRequest req = WebRequestFactory.Create

("http://www.amazon.com");

		WebResponse result = req.GetResponse();

		Stream ReceiveStream = result.GetResponseStream();



		Byte[] read = new Byte[512];

        	int bytes = ReceiveStream.Read(read, 0, 512);

        

        	while (bytes > 0) 

	       	{

			Response.Write

(System.Text.Encoding.ASCII.GetString(read, 0, bytes));

         	  	bytes = ReceiveStream.Read(read, 0, 512);

	       	}

	}



</SCRIPT>
