SYMPTOMS
When your browser submits a POST request to an Active Server Pages (ASP) Web page through Microsoft Internet Security and Acceleration (ISA) Server 2004, you may receive a blank page in response.



CAUSE
This problem may occur if the following conditions are true:
 * Your ISA Server 2004-based computer is configured with a Content-Type-based rule.
 * The Content-Type-based rule applies to HTTP traffic that is evaluated when the POST request is processed.
 * The POST request that is made by the client is an HTTP 1.1 request.
 * The Web server sends back an &quot;HTTP 100 Continue&quot; response before it sends the &quot;HTTP 200&quot; response together with the response data.
