I assume your purge is not hashing properly. When you purge it has to match whatever it hashed on when the obj went into the cache.
I have problems using the standard sub vcl_hash so I hash only on the URL and not the hostname so this let's me purge from outside of the "restricted area." In your case I think you probably need to purge all possibilities based on that X-header you are setting. If that gets too difficult I fallback on doing a BAN instead.
