ISA Blocks http response from external server
Hi Experts,
I am trying to call an external web page from our internal intranet using ASP/VBScript but ISA Server seems to be blocking the request.
This is the message ISA Server returns:
Error Code: 403 Forbidden. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)
IP Address: **********
Date: 11/12/2007 11:49:44
Server: Our Internal Server
Source: proxy
The code that I use is:
Dim url
Dim oXMLHttpRequest
url = "url goes here"
Set oXMLHttpRequest = Server.CreateObject("Micro
oXMLHttpRequest.open "POST", url, false
oXMLHttpRequest.setRequest
oXMLHttpRequest.setRequest
oXMLHttpRequest.send
If oXMLHttpRequest.responseTe
Response.Write("Error Code: " & oXMLHttpRequest.responseTe
End If
Set oXMLHttpRequest = Nothing
We have tried setting up rules as described at http://articles.techrepublic.com.com/5100-6350_11-6029304.html but this does not solve the problem either. Anybody have any idea what the problem is?

The ISA Server, by default, only allows traffic to certain sites. There's a system policy that only lets you access certain sites like windowsupdate.com, microsoft.com. Have you tried adding the target URL to the policy to see if that resolves it?

Hi LOOM,
Do you where I can check this list of allowed sites is ISA? This site would be a site that we post to and receive responses back from.
Thanks.

Sweet, cheers LOOM that worked a treat! I added the domain for the site in question and ISA then allowed me to post and get a response from that domain using a XMLHTTP Request.
