Issue
The problem one of our customer's is experiencing with eBook downloads is due to a proxy server or firewall problem. How do they fix it?
Solution
Their network administrator will have to look at the settings for their proxy server or firewall and the associated logs and see what setting is blocking or caching Adobe Reader's HTTP headers.
This will involve detective work on the part of the network administrator. The only instruction to the network admin is that it appears that something on your network--probably a proxy server or firewall is caching or blocking Reader's HTTP headers.
- Make sure the firewall is using port 80 and NO CACHE is on
- Make sure that the firewall allows your browser and Reader/Acrobat to connect to http://aractivate.adobe.com
Here's the list of all the HTTP headers Reader uses--open them for both directions. The ports are the standard HTTP ports. (Reader doesn't use SSL.)
