Recieving Blank Pages - 27.Oct.2004 6:46:00 PM

Status: offline 		I just brought up ISA 2004 to replace a current ISA 2000 server on the new box I am able to browse the web but on certain links all I get is a blank page with the word done at the bottom. When I switch to ISA 2000 proxy the link
works fine. An example of this is on HPs website in the driver section and on yahoo while clicking on the inbox.

Any help would be great.

May I ask what your connection type is? It might be dealing with mtu

We got a similar problem using ISA server 2004. Some pages just doesn't load. We are also connecting to a PIX firewall. Most pages that doesn't load on our side as basically .asp or .aspx pages. Our installation was also on new hardware and i have also tried switching off the caching - no luck.

Any additional ideas?

Thanks
Eldridge

Disabling content filtering rules is the only workaround.

If anyoen comes up with a good solution please post it.

 Hello!

I too am here to report that SP1 doesn't solve this issue. I am also behind a Cisco 506 PIX and which is on a T1.

If anyone has any ideas, I would be happy to try it!

I have worked around it be making a url set that includes the pages with the problems and having it in the exceptions for the destination hope this helps. I really wish I would have found this problem earlier when I was evaluating the product would have never purchased it. Also having a problem where funny mime types like application/x-msdos-program will allow an executable through even with application content filtering on and blocking the .exe extention.

Status: offline 		Hi guys,

1. Remember, the Web server is responsible for reporting the MIME type -- there is no magical method that the firewall can use to come up with a MIME type on its own

2. If you're blocking file extensions, some site URIs include those extensions after the host name. That is the case with Yahoo mail.

HTH,
Tom

Status: offline 		OK, sigh, it looks like this will not be solved in the near future. I know of a dozen school districts here in East Texas in the same boat as the previous posts. TheyÆre all sitting behind Pix and Websense. What changed between ISA 3 & 4 that causes error 64 when behind Pix or Websense? Or maybe I should ask what would be the best path, for me, to take to find a solution.

Thanks, William

What is the actual problem you're experiencing? I've never seen it and I don't know how to replicate it. Give me a clue.

Thanks!
Tom
