Parsing functions can be used to maintain state information during
load
testing and to simulate real-world user-data input.
Parsing functions (which are stored in BDL variables) read
session-related values in server responses. They then use parsed values as
parameterized data that is sent back to servers as part of a query string post
or URL data.
Note: Parsing functions are different from verification functions, which
only check for the presence of specified input values.
