The Netscape Web browser implements a proprietary technology known as Server Push to send a type of dynamic page updates to a client. This technology is not supported by Microsoft Internet Explorer. However, you can use Server Push with Microsoft Active Server Pages (ASP), or you can Client Pull as an optional method of displaying dynamic page updates in Internet Explorer.

Server Push Using ASP
To implement Server Push using ASP, do the following:
Save the following code as Push.asp in a folder with at least Script access defined:
<% @Language="VBScript" %><% Option Explicit Dim strBoundary ' change the following string to whatever boundary you wish to use strBoundary = "MSBOB" ' turn off buffering Response.Buffer = False ' set the content type as a multipart document Response.ContentType = "multipart/x-mixed-replace;boundary=" & strBoundary ' create a function to output the boundary Sub WriteBoundary() Response.Write "--" & strBoundary & vbCrLf Response.Write "Content-Type: text/html" & vbCrLf & vbCrLf End Sub ' this is a very unelegant sleep function just to create a short delay Sub Sleep(tmpSeconds) Dim dtmOne,dtmTwo dtmOne = Now() While DateDiff("s",dtmOne,dtmTwo) < tmpSeconds dtmTwo = Now() Wend End Sub%><% WriteBoundary %><html><body><p>First Page</p></body></html><% Sleep 10 WriteBoundary%><html><body><p>Second Page</p></body></html><% Sleep 10 WriteBoundary%><html><body><p>Third Page</p></body></html>
Browse to the page using the Netscape Web browser. The following behavior should occur:
The first page displays for 10 seconds, and the browser indicates that it is still loading a document.
The second page displays for 10 seconds, and the browser continues to indicate that it is still loading a document.
The third page displays, and the browser indicates that the document loading has completed.
