Maybe you could do this with tomcat configuration:
http://tomcat.apache.org/tomcat-5.5-doc/config/http.html

Check maxThreads and acceptCount

You can also look at the viewer properties file:
# Maximum number of simultaneous viewing sessions that can be open at the
# same time, to prevent cache overflowing through multiple requests.
# A value of 0 means no limit.
viewer.session.maximumSessionCount=0

# Behavior that must be used once the maximum session count is reached
# (if different than 0):
# - A value of 0 will use the "Discard new session" policy that will show
# an error message for all the newer sessions.
# - A value of 1 will use the "Discard the oldest session" policy that will
# try to discard the oldest session, even if it has not expired yet.
# Note that "busy" sessions (for example downloading results) won't be
# cleant by this mechanism.
viewer.session.maximumSessionCountPolicy=1

Thank you Jason.

I updated viewer.session.maximumSessionCount=5 in web-inf/viewer.properties and it works like a charm!
