Citrix Web Interface 4.6 - Unable to download ICA Web client

[icebun007_]

I am running a SA2500 on 6.1R4 and have a Citrix Web Resource setup, pointing to a LAN based Citrix Web Interface 4.6 server with auto client detect turned on.

If I sign on locally on the LAN at the URL address, I can download the client following detection.

When I go through the SA (ie externally), I can run through the client detect but I get an error when attempting to download the client.

The message reads "Internet Explorer cannot download DanaInfo=nameofmyserver+ica32web.msi from myvpnwebsite.com"

Has anyone seen this. I thought it was a firewall issue but I have a open rule for all DMZ traffic from the SA to the the LAN.

Thanks.

We had to implement a caching bypass policy for the msi such as http://*:*/*msi* and set it to Unchanged (do not add/modify caching headers). We also had to create a ReWrite policy to prevent the rewriting of the download as well. We set the resource to the URL of the MSI and chose Don't rewrite content: Redirect to target web server.

Hope this helps.

Thanks Mercy Mark.

It's done the trick.

this fixed our problem as well! Thanks!. Tried everything, WSAM, NC, etc none of which would let the client get back to the user. I would like to understand WHY this enabled the solution to work if anyone cares to comment.

THANKS!
