ASP wrapper and HTTP GET requests

[Brent Fraser]

Tom,

  Your code is pretty close.  I made one minor change by commenting-out the
second strRequest assignment:

<%
    Server.ScriptTimeout = 360

    Select Case Request.ServerVariables("REQUEST_METHOD")
      Case "GET"  strRequest = Request.QueryString
      Case "POST" strRequest = Request.Form
    End Select

'   Remove the following line:
'    strRequest = Request.ServerVariables("QUERY_STRING")

    strURL =
"http://myserver/cgi-bin/mapserv.exe?map=C:\Inetpub\wwwroot\workshop\itasca.
map&" & strRequest

    Dim objHTTP
    Set objHTTP = Server.CreateObject("MSXML2.ServerXMLHTTP")
    '
    ' will this line below work for POST requests? YES!
    '
    objHTTP.open "GET", strURL, false

    objHTTP.send ""
    Response.ContentType = objHTTP.getResponseHeader("content-type")
    Response.BinaryWrite objHTTP.responseBody
    Set objHTTP = Nothing


%>

This works with the Itasca demo in workshop.zip (with index.html using "GET"
or "POST" ); I haven't tested it with WMS yet.

Thanks for the info.

Bug 1253 does not have a template problem.  What's happening is that the
POST request is sent to ASP script, which passes as a GET request with
no arguments.

Can someone try this out and verify this works?  Also see comment line
below in the code:

  <%
    Server.ScriptTimeout = 360
    Select Case Request.ServerVariables("REQUEST_METHOD")
      Case "GET" strRequest = Request.QueryString
      Case "POST" strRequest = Request.Form
    End Select
    strRequest = Request.ServerVariables("QUERY_STRING")
    strURL =
"http://myserver/cgi-bin/mapserv.exe?map=C:\Inetpub\wwwroot\WMS\mymap.ma
p&" & strRequest
    Dim objHTTP
    Set objHTTP = Server.CreateObject("MSXML2.ServerXMLHTTP")
    '
    ' will this line below work for POST requests?
    '
    objHTTP.open "GET", strURL, false

    objHTTP.send ""
    Response.ContentType = objHTTP.getResponseHeader("content-type")
    Response.BinaryWrite objHTTP.responseBody
    Set objHTTP = Nothing
  %>
