Unable to Download an Office File from a Published Server

image There are a lot of scenarios where users have problem downloading documents from a Web server published by an ISA firewall. Most of them I hear about are related to SharePoint related issues. However, SharePoint isn’t always the villain – as seen in a recent blog post by Yuri Diogenes.

In this scenario, the external user terminated the connection at the ISA firewall’s external interface using HTTPS (SSL). The connection from the ISA firewall to the Web server uses HTTP, making this an SSL to HTTP bridging scenario.

The user could not download the file from the outbound using SSL to HTTP bridging, but a user on the internal network using HTTP only was able to download the file fine.

Reviewing the Firewall logs and the Web Server logs showed no problems in those areas either.

So where was the problem? Maybe on the client side. But the client is using SSL from itself to the Web Listener on the ISA firewall – how will you be able to find out what’s going on there?

You’ll have to check Yuri’s post to find out. Find it at:
