title: AWS application load balancer listener rule paths
body: <p>Configuring an application load balancer.</p>
  
  <p>I have 3 separate target groups and about 30 different paths I'd like to filter on.</p>
  
  <p>When filling out <code>path pattern</code> what are the possible values? Given it's called "pattern" gives the impression it can accept regex but validation is preventing this.</p>
  
  <p>Is it possible to match multiple paths to a target group or will I have to create a separate rule for each path?</p>
  
  <p>I realise using an additional level in my paths (ie /group1/path, /group2/path) would simplify this but looking at if there's an easy solution for current architecture I've inherited.</p>
