A brief explanation about willingness value
It is possible to have slower machines take a smaller number of requests than faster machines.
This is done with the "WillingnessValue" found in the web.cfg for a host.
This variable accepts a number from 0 to 10.
The higher the number, the more likely the host will be used.
If a system administrator elects to use a webdirector, he or she configures each individual webengine with the slump name of the webdirector and a willingness value, which is a number from 0 to 10 that represents the webengine's willingness to accept user sessions.
When each webengine starts, it registers itself with the webdirector and passes its configured willingness value.
This variable is not used if the webengine is not configured against a Web Director.
