Hello,

I've noticed that running a delete operation through a proxy with disk caching enabled (PSS + PFC components) goes through and deletes the file from the origin but the local copy is still kept.

Setup:
client --> proxy (with cache) --> origin

Steps to reproduce:

  1. write file from client to origin
  2. read file from proxy (file gets cached)
  3. send delete command to the proxy (file gets deleted on origin)
  4. read file from proxy (local copy is served)

Log messages from the proxy:

I supposed the expected outcome would be for the file to get deleted from the cache as well.
