You could do this through the F5 health monitoring mechanism.
Essentially, have a programme running on each of the 3 back-end servers and counting user sessions. If the number of user sessions reaches 50, the programme will write to a file accessed by the F5 monitor to cause that app server to be marked down by F5. Existing connections will continue, but new connections will be sent to the other back-end servers.
