Issues using VMware Blast 6.0

Hi

 

We are experiencing some Blast issues after our upgrade to View 6.0.

If you are behind a proxy/waf, Blast does not function at all, on a 'transparent' connection, everything works as expected.

Before the upgrade we were using version 5.3.

 

I pinpointed the problem to step 4:

Step 1: Go to the blast URL (port 443)

Step 2: Enter credentials

Step 3: Pick the desktop

Step 4: Redirect to the actual desktop (port 443)

 

We used PAT to translate the 8443 port to 443 to avoid problems with port-based firewalls.

 

Using the debug mode in IE, we found that, if you are behind the proxy, the last packet is a 'GET' with a '101 switching protocol' header.

According to some sites, the 101 packet can result in connectivity errors if the proxy does not conform to the HTTP standards.

 

Unfortunatly, we are not getting help from the parties with the proxy, they are not allowed to provide us with logging so we cannot see what is happening on those proxies/web application firewalls.

 

We followed KB2046427, KB2056649 & KB1028332

A newly, fresh installed environment based on 6.0 is also not functioning.
