Tomcat via Apache Reverse Proxy

An Apache reverse proxy architecture provides for a number of features that may be desirable for some deployment environments:

  • Load balancing capabilities via mod_proxy_balancer
  • Improved SSL/crypto handling via OpenSSL or SSL offloading via custom hardware

The Apache proxy documentation may be a helpful reference for the discussion in the following sections.
