Blocking Websites From Your Web Server Cache
If your web server is set up to act as a proxy, you can prevent the server from caching
objectionable websites.
Important: To take advantage of this feature, client computers must specify your web
server as their proxy server in their browser preferences.
You can import a list of websites by dragging it to list of sites. The list must be a text file
with the host names separated by commas or tabs (also known as csv and tsv strings).
Make sure that the last entry in the file is terminated with a carriage return/line feed, or
it will be overlooked.
To block websites:
1 In Server Admin, click Web for the server you want.
2 Click Settings in the button bar.
3 In the Proxy pane, click Enable Proxy.
4 Do one of the following:
• Click the Add button, type the URL of the website you want to block in the Add field,
and click Add.
• Drag a list of websites (text file in comma-separated or tab-separated format) to the
“Blocked hosts” field.
5 Click Save.
Web service restarts.
Using Secure Sockets Layer (SSL)
Secure Sockets Layer (SSL) provides security for a site and for its users by
authenticating the server, encrypting information, and maintaining message integrity.
About SSL
SSL was developed by Netscape and uses authentication and encryption technology
from RAS Data Security, Inc. For detailed information about the SSL protocol, see:
• www.netscape.com/eng/ssl3/draft302.txt
• http://developer.netscape.com/misc/developer/conference/proceedings/cs2/
index.html
The SSL protocol is on a layer below application protocols (HTTP, for example) and
above TCP/IP. This means that when SSL is operating in the server and the client’s
software, all information is encrypted before being sent.
The Apache web server in Mac OS X Server supports SSLv2, SSLv3, and TLSv1. More
information about these protocol versions is available at www.modssl.org.
