A few observations after a quick glance:

  1. Instead of 
    starts_with
    I would recommend matching (i.e. 
    eq
    ) the actual host. This avoids issues if another instance is added at some point.
  2. The FQDN you're using is invalid. Although I assume it's a placeholder, make sure you drop the slash (
    /
    ).
  3. The path you're matching (
    /dev
    ) may be too limited. Keep in mind that other valid matches may include 
    /dev/
    , 
    /dev/index.html
    , et cetera. This would be a good candidate for 
    starts_with
    .
  4. I would group the header manipulations. In other words, move the pool selection to the bottom.
