Chapter 67 Clientless SSL VPN
Character encoding, also called "character coding" and "a character set," is the pairing of raw data (such
as 0s and 1s) with characters to represent the data. The language determines the character encoding
method to use. Some languages use a single method, while others do not. Usually, the geographic region
determines the default encoding method used by the browser, but the remote user can change it. The
browser can also detect the encoding specified on the page, and render the document accordingly.
The encoding attribute lets you specify the value of the character-encoding method used on the portal
page to ensure that the browser renders it properly, regardless of the region in which the user is using the
browser, and regardless of any changes made to the browser.
By default, the adaptive security appliance applies the "Global Encoding Type" to pages from Common
Internet File System servers. The mapping of CIFS servers to their appropriate character encoding,
globally with the "Global Encoding Type" attribute, and individually with the file-encoding exceptions
displayed in the table, provides for the accurate handling and display of CIFS pages when the proper
rendering of filenames or directory paths, as well as pages, is an issue.
Fields
Global Encoding Type —This attribute determines the character encoding that all clientless SSL
•
VPN portal pages inherit except for those from the CIFS servers listed in the table. You can type the
string or choose one of the options from the drop-down list, which contains the most common
values, as follows:
–

Note

–
You can type a string consisting of up to 40 characters, and equal to one of the valid character sets
identified in http://www.iana.org/assignments/character-sets. You can use either the name or the
alias of a character set listed on that page. The string is case-insensitive. The command interpreter
converts upper-case to lower-case when you save the adaptive security appliance configuration.
• CIFS Server—Name or IP address of each CIFS server for which the encoding requirement differs
from the "Global Encoding Type" attribute setting.
A difference in the encoding of the CIFS server filename and directory indicates that you might need
to add an entry for the server to ensure the encoding is correct.
• Encoding Type—Displays the character encoding override for the associated CIFS server.
• Add—Click once for each CIFS server for which you want to override the "Global Encoding Type"
setting.
• Edit—Select a CIFS server in the table and click this button to change its character encoding.

If you click none or specify a value that the browser on the clientless SSL VPN session does
not support, it uses its own default encoding.
