Compatibility issue with Microsoft Automated Troubleshooting Services(MSDT) application and Proxy Redirect.

Products

• ProxySG Software - SGOS

Issue/Introduction

Microsoft Automated Troubleshooting Services(MSDT) application will not work through the ProxySG when the ProxySG is doing off-box content filtering, or when the ProxySG sends a “302” response code back.

Resolution

 Microsoft Automated Troubleshooting Services(MSDT) application will makes HTTPS requests to the following Microsoft URL’s when it is initiated.

• support.microsoft.com
• go.microsoft.com
• diagnostics.support.microsoft.com
• dcodews.partners.extranet.microsoft.com
• dcupload.microsoft.com

 

The application is excepting a “200” back from the upstream, so if the ProxySG sends a “302 Redirect,” the application doesn’t understand, and it breaks.

 

To get the application to work, disable the off-box content filtering and proxy authentication with the follow CPL.

 

<proxy>

Condition=MSDT_URL authenticate(no)

 

<Cache>

Condition=MSDT_URL request.filter_service(no)

 

define condition MSDT_URL

url.domain=support.microsoft.com

url.domain=go.microsoft.com

url.domain=diagnostics.support.microsoft.com

url.domain=dcodews.partners.extranet.microsoft.com

url.domain=dcupload.microsoft.com

end
