/**
*
* Match against the request's JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client
* Hello of an incoming request. This fingerprint serves as a unique identifier for the client's TLS configuration. WAF
* calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the
* calculation. Almost all web requests include this information.
*
*
*
* You can use this choice only with a string match ByteMatchStatement with the
* PositionalConstraint set to EXACTLY.
*
*
*
* You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the
* fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF
* Developer Guide.
*
*
* Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any
* future requests that have the same TLS configuration.
*
*

* Documentation
