A computer network environment (10) allowing connection of a client system (36) to a legacy host system (18,19) using a server (26) is provided. The computer network environment (10) includes a legacy host system (18,19) having TCP/IP connectivity. The legacy host system (18,19) is operable to support a terminal session for access to the legacy host system (18,19). The computer network environment (10) also includes a server (26) operable to communicate with the legacy host system (18,19) across a persistent TCP/IP socket connection (30). The computer network environment (10) further includes a client system (36) executing an applet process (42) under a web browser (38). The applet process (42) is operable to communicate with the client thread (28) across another persistent TCP/IP socket connection (44) and is operable to provide a terminal session to a user of the client system (36). This terminal session is supported by a persistent connection allowing real-time bidirectional communication with the legacy host system (18,19), including response time monitoring, enabled by appropriate response time monitoring tool executing on host system 18 and appropriate protocol conversions at server (26).
