title: Java servlet Filter with multiple values in FilterConfig? Is it possible?
body: <p>I'm trying to implement a servlet filter that would ignore some URL's while filtering everything else.
  Wanting to make it flexible, I tried to set the excluded URL's as FilterConfig params. Though, in the server configuration, the filter params section doesn't seem to accept multiple values for a given param name, so I'm kind of stuck wondering if and how to include several values that I can then receive as a Set or Array in the filter init().</p>
  
  <p>Here's basically what I'm after:</p>
  
  <p><code>&lt;filter&gt;
        &lt;filter-name&gt;RequestFilter&lt;/filter-name&gt;
        &lt;filter-class&gt;...RequestFilter&lt;/filter-class&gt;
        &lt;init-param&gt;<br>
          &lt;param-name&gt;ignoredUrls&lt;/param-name&gt;<br>
          &lt;param-value&gt;/url1&lt;/param-value&gt;
          &lt;param-value&gt;/url2&lt;/param-value&gt;
          &lt;param-value&gt;/url3&lt;/param-value&gt;
        &lt;/init-param&gt;<br>
      &lt;/filter&gt;</code></p>
  
  <p>Of course I can use a delimiter-splitter approach, but I'm wondering if there is some sort of standardized way of doing that.</p>
  
  <p>Thanks a lot!
