13 +* **HTTP Adapter** - This is an application that serves as the interface between your web server and your application instances. The HTTP adaptor routes requests from the web server to the appropriate application instance and sends the responses generated back to the web server. The adaptor does this while performing load balancing to distribute an application's users among its active instances. Load balancing helps to spread the user load of your site evenly across your application hosts.

27 +Andrew Lindesay has written an open-source [[AJP>>http://en.wikipedia.org/wiki/Apache_JServ_Protocol]] adaptor for WebObjects 5 which should allow you to deploy your WebObjects application without servlets or the 'wotaskd' infrastructure. Such a deployment is most easily achieved with versions of the Apache HTTP server 2.2 or better as they have built-in support for load-balancing and AJP request-forwarding.

29 +This adaptor is distributed under the [[LEWOStuff>>LEWOStuff-Overview]] open-source framework. It is however stand-alone and has no direct dependency on other libraries or frameworks other than obviously WO 5. For more details on this, see the relevant section of the PDF overview supplied with the LEWOStuff framework.
