Hello, 

Here is the entire log entry for a failed attempt:

Now I rename the file to mytest.tar.zip and try again successfully.

Attempting to download files with either .gz or .z extensions fails.  A
direct connect to web8 always allows the download.

Thanks

The request is not palatable to ISA.
What is the *entire* log entry for that denied request?

Some Additional Information

 

Looking at the ISA Log when trying to download this file I see Failed
Connection Attempt under the Action Column. In addition the web browser
displays the following error.

 

Technical Information (for support personnel)

*       Error Code: 500 Internal Server Error. The request is not supported.
(50) 

 

I can browse the parent directory just fine. This error only occurs when I
attempt to download a file.   The file does have a double extension in this
case: myfile.tar.gz

 

Thanks

Bill

Subject: [isalist] Can not dowload file via http

 

http://www.ISAserver.org

Hello,

 

I am trying to download a file via http: and I receive the following message.
Internet Explorer cannot download  myfile.tar.gz from www.myserver.com
<http://www.myserver.com/>   Internet Explorer was not able to open this
Internet Site. The requested site is either unavailable of cannot be found.
Please try again later.

 

This file is on a published web server. I can download the file from the
source server but not when it is published through ISA.  I don't "believe"
that I have any content restrictions setup for the publishing rule in
question.  I even we so far as to allow windows executables to download.

 

What might cause this behavior in ISA 2004. Is there a global configuration
that I am missing that would block files like this?

 

Thanks


Bill
