Issue/Introduction:
If using a PC with Windows 8.1 and Internet Explorer 11, access to some HTTPS sites does not work.
Cause:
This issue can occur if the site wants to use TLS session tickets. If the server sends back a server HELLO that contains a TLS session ticket, the connection fails.
Resolution:
Blue Coat is currently working on a fix for this issue in the following SGOS versions and bug numbers:
- SGOS 6.5 - B#211683
- SGOS 6.2 - B#211676
Workaround
Disable protocol detection for the sites that are affected or enable disable protocol detection for all HTTPS sites:
Per affected site:
<proxy>
url.domain="domain.com" detect_protocol(no)For all HTTPS sites:
define condition __SSLPort
url.port=443
end condition __SSLPort
<proxy>
condition=__SSLPort detect_protocol(no)
