Method Detail

init

public void init(javax.servlet.FilterConfig config)
          throws javax.servlet.ServletException

Load all of the headers from the config. The headers will be in one of the following forms:

    <init-param>
     <param-name>SomeHeader</param-name>
     <param-value>SomeValue</param-value>
    </init-param>
 

-or-

    <init-param>
     <param-name>SomeHeader:n</param-name>
     <param-value>SomeValue</param-value>
    </init-param>
 

Where n is some arbitrary value that provides uniqueness since the servlet API doesn't allow for duplicate headers.
