boruc:

Also you should not be manually (or even with a Script) editing cache
objects on disk as a routine operation. As Alex already mentioned use
ICAP or eCAP adaptation for that instead - thats one reason why those
adaptation APIs exist.

As I noted in the other email you have to fully stop Squid and restart
with a VERY SLOW full-disk scan of the cache after editing disk objects
to prevent the metadata being mismatched and your edit thrown away. So
dont do it unless its a one-off situation. Even then simply deleting the
bad object and letting Squid find a new copy on next request is better
than editing.
