Dynamic TLS Record Size is a feature that makes it possible to optimize the size of TLS data sets (records) for better performance and greater security. Normally, the size of the TLS records is statically determined by the application or the server and is therefore the same for all data transfers.
With Dynamic TLS Record Size, however, the sizes of the TLS records can be dynamically adapted to the data transmission conditions. For example, if the network connection is poor, smaller TLS records can be used to increase transmission speed and reduce overhead. With a good connection, larger TLS records can be used to increase transmission efficiency.
Using Dynamic TLS Record Size can improve the performance and security of HTTPS connections by allowing better adaptation to network conditions and making potential attacks more difficult. However, Dynamic TLS Record Size is not supported by all TLS implementations and may not be compatible with older browsers or servers.
