NOTE: If the RICH
Expression field is blank,
XML expressions will be
ignored. If desired, you
can type an asterisk (*) as
a wildcard in the RICH
Expression field to accept
all RICH expressions
Also, you cannot use the
vertical bar ( | ) or the
carat (^) in XML
expressions.
2. In the RICH Expression field, type a valid RICH expression.
3. (Optional) In the Doc # field, type a valid document number if
using multipart or URL-encoded messages. The entry must be
an integer, and the valid range is from 1 to 99. If a document is
not specified, the SA8250 starts with the first XML document in
the message.
4. In the XML Expression field, type a valid XML expression.
5. To the right of the XML Expression field, click the checkbox.
Your RICH and XML expressions are added to the list.
6. Repeat steps (2) through (5) above as needed.
7. When you have finished adding expressions to the list, add the
expressions to the SA8250’s configuration by clicking Apply.

XML Default Special Case
We recommend programming the SA8250 with one of your servers
set to the default special case.
Typing the XML Default Special Case
The advantage of this is that if no XML expressions match, the client
is directed to the server you chose as the default server.
If no default servers exist, and no RICH or XML expressions match,
the client will receive a “Server not found” error from the SA8250.
