Once you have installed Apache 1.3.x, you have in your conf directory an
httpd.conf file which contains the lines:

#   Inter-Process Session Cache:
#   Configure the SSL Session Cache: First the mechanism 
#   to use and second the expiring timeout (in seconds).
#SSLSessionCache        none
#SSLSessionCache        shmht:/usr/local/apache/logs/ssl_scache(512000)
#SSLSessionCache        shmcb:/usr/local/apache/logs/ssl_scache(512000)
SSLSessionCache         dbm:/usr/local/apache/logs/ssl_scache
SSLSessionCacheTimeout  300

(In the case of Apache 2.0.x, these lines would be in ssl.conf, and you
wouldn't be using modssl, since that is built into the Apache 2.0
distribution already.)

The best performance session caching comes if you change these lines to:

#   Inter-Process Session Cache:
#   Configure the SSL Session Cache: First the mechanism 
#   to use and second the expiring timeout (in seconds).
#SSLSessionCache        none
#SSLSessionCache        shmht:/usr/local/apache/logs/ssl_scache(512000)
SSLSessionCache        shmcb:/usr/local/apache/logs/ssl_scache(512000)
#SSLSessionCache         dbm:/usr/local/apache/logs/ssl_scache
SSLSessionCacheTimeout  300

to turn on the shmcb session cache instead of the dbm one.  However, in
order for this to work, you will likely need to use the MM package (which
can be downloaded from http://www.ossp.org/pkg/lib/mm/ - see that site for
further information about this package).

Can you give me pointer on description of these configuration directives.

Thanks
