The Formatting Value Wizard is a popup window available from both the Insert/Edit/Copy pages and the Insert/Edit pages. The wizard simplifies entry of xl-formatted strings, which require specific syntax coding. Both Log and Add Header functions require xl-formatted string coding.
An xl-formatted string can contain references to the state of the server, or to the message being processed. For example, %@ruri.user refers to the user part of the Request URI within an xl-formatted string. The references are replaced with their actual value before the log message is issued, or before the string is appended to the Request.
Accessing request content during an Answer processing feature provides a read only access to all AVPs in the request message while processing an answer message to all answer trigger points.
