Greetings!

When I try to download any file with content type marked at "Use progress notification instead of the default content delivery method for the selected content types", my browsers does not show "Progress Notification" page. The download progress is still going as "Standard trickling".

Maybe somebody faced with that problem before?

Hi,

What's your web browser?

Progress notifications are not displayed when content is downloaded over an HTTPS connection.

You can specify the types of content for which Forefront TMG sends progress notifications by including MIME types and file name extensions in the predefined Content Types Displaying Progress Notifications content type set. By default, this content type set contains MIME types and file name extensions for compressed files and executable files, which cannot be displayed in typical Web browsers.

Hi, Joyce L!

We use IE8/11, Chrome, Firefox - latest versions.

Sometimes Notifications works, but I can't understand the reason when it works and when not.

Yes, I know about HTTPS, but I try to download EXE or ZIP files from HTTP sites. And still no notification page...

Hi,

Have you checked the TMG logging and Eventlogs on the clients when notification not works? Any error?

Best Regards,

Joyce

There is no errors on server or client logs...

So, Downloading works fine, but without notification page. Just standard trickling.

And you have checked that these files are listed in "Content Type Exceptions"?

Have you tested this with pretty large files? It may be that the files are downloading so quickly that notification is not necessary.

I will be honest, I have not personally seen any issues in the past.

Is there a particular reason why the notification is important to you/your end users? Just curious.

Hi, Keith!

Thank you for your answer.

I tested big files (up to 1 GB) and small (up to 1-2 MB) with same result.

But I find some strange regularity: some files from HTTP are downloaded fron Progress Notification, and some with Standard Trickling.

For example:

With Progress Notification:

Without:

http://dl.mediacoderhq.com/files/MediaCoder-x64-0.8.34.5715.exe

What the difference between them?

P.S.: I just want to understand how it works. Why some times it should work, but it didn't? And yes, our Users don't like Standard Trickling, because they think than "internet is slow")))
