Before you record a session, VuGen allows you to specify a language for script generation. The available languages for script generation vary per protocol. The most common available languages are C and Java. By default, VuGen generates a script in the most common language for that protocol, but you can change this through the Script recording options node.
For user interface details, see General > Script recording options.
Tip: If you record a script in one language, you can regenerate it in another language after the recording. For task details, see Regenerate a Vuser script.
After you select a generation language, you can enable language-specific recording options which instruct the recorder what to include in the script and how to generate it.
If at least one of the protocols you are recording has multi-protocol capabilities, the Script node will be available except when you record HTTP or Winsock as a single protocol script.
