Internet Explorer file downloads over SSL VPN

[ Edited ]

I’m using a SSL VPN model SA-4000 with the version 6.2R1 (build 13255) to provide access to an internal WEB portal. In the configuration is defined a role with the web enable settings.


Using the Internet Explorer 6 or 7, when a user accesses to the portal through the SSL VPN and tries to download a file (.xls) appears the error with the message “The file could not be written to the cache” and it’s not possible to open or save the file to disk.

 

This problem doesn’t happen in Mozilla and when the access is done directly to the portal.

Re: Internet Explorer file downloads over SSL VPN

What you are seeing is Internet Explorers annoying handling of Cache-control headers. If IE receives a no-cache header, it will refuse to write the file to the cache and thus it cannot be opened by external applications (excel, pdf,..). IE only does this when accessing websites over SSL, not over plain HTTP.

 

Check the caching resource policy configured on your SSLVPN. Is it set to smart caching or no-cache for this application?

Re: Internet Explorer file downloads over SSL VPN

I haven't caching autopolicy defined.

Now i defined a policy with action field "no-cache-no-store" and it works!

Thanks.
