Descriptions
On versions 15.0.x before 15.1.0 and 14.1.x before 14.1.4, the BIG-IP system provides an option to connect HTTP/2 clients to HTTP/1.x servers. When a client is slow to accept responses and it closes a connection prematurely, the BIG-IP system may indefinitely retain some streams unclosed. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
En las versiones 15.0.x anteriores a 15.1.0 y 14.1.x anteriores a 14.1.4, el sistema BIG-IP ofrece una opción para conectar clientes HTTP/2 a servidores HTTP/1.x. Cuando un cliente tarda en aceptar respuestas y cierra una conexión prematuramente, el sistema BIG-IP puede retener indefinidamente algunos flujos sin cerrar. Nota: No se evalúan las versiones de software que han alcanzado End of Software Development (EoSD).
