  • They can be adapted if their default setting does not fit customer needs:
  • EnvVarCookiePrefix "AL_ENV_"
  • EnvVarCookiePlainChars "!#$&*-./0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ^_`abcdefghijklmnopqrstuvwxyz|~"
  • ClientFingerprinting.EnvVarCookieExport.Enable "TRUE"
  • SessionVariable.EnvVarCookieExport.Enable "TRUE"
  • SessionVariable.EnvVarCookieExport.Name.Pattern ".*"

We do not recommend changing the environment cookie prefix, as this is a common source of confusion.
