[Directive] JkWorkerProperty [Description] 
Enables setting worker properties inside Apache configuration file. The syntax is the same as in the JkWorkersFile (usually workers.properties). Simply prefix each line with "JkWorkerProperty" to put it directly into the Apache httpd config files. This directive is allowed multiple times. It must be put into the global part of the configuration. If you don't use the JkWorkerProperty directives, then you must define your workers with a valid JkWorkersFile. There is no default value. This directive is available in jk1.2.7 version and later.
