maybe some obvious error but when i want to login to Oracle Metalink following happens:
go to oracle.com, on the top right on your screen click n "I want to download patches"
There is no block at all, even *.oracle.com is in the global URL whitelist.
Clicking the download link opens the login page correctly. This happens with all Browsers (Chrome, Firefox, IE)
Someone had such a "phenomen" before?
I have not seen this bevaior previously! On a quick thought, can you check your access.log what media type this token is? In case it is not HTML then this might lead to progress page based downloads.
