[Doc] WMS ASP wrapper script example does not support POST

[tomkralidis]

On Page:

http://mapserver.gis.umn.edu/doc/wms-server-howto.html#onlineresourceurl

..the ASP wrapper example only handles GET type requests, not POST.

We need to update this code snippet to correctly handle GET and POST, and then
update the documentation.

Reassigned bug to Jeff who is the maintainer of this howto.

Tom: Can you please paste the new script in this bug?

The script below, while functional, is intended only as an example of using ASP 
to filter Mapserver requests.  Using ASP in a production WMS server will likely 
require additional ASP especially in the area of error handling and setting 
timeouts.

<%
    Server.ScriptTimeout = 360
        
    Select Case Request.ServerVariables("REQUEST_METHOD")
      Case "GET"  strRequest = Request.QueryString
      Case "POST" strRequest = Request.Form
    End Select
    
    strURL = "http://myserver/cgi-bin/mapserv.exe?
map=C:\Inetpub\wwwroot\workshop\itasca.map&" & strRequest
    
    Dim objHTTP
    Set objHTTP = Server.CreateObject("MSXML2.ServerXMLHTTP")
    objHTTP.open "GET", strURL, false
    objHTTP.send ""
    
    Response.ContentType = objHTTP.getResponseHeader("content-type")
    Response.BinaryWrite objHTTP.responseBody
    
    Set objHTTP = Nothing
%>
