[squid-users] How to clear cache at remote server?

Hi,

Consider the following setup:

------------------------------
ServerA (Apache, PHP)

ServerB (Squid)
ServerC (Squid)
ServerD (Squid)
------------------------------

ServerA will execute the php scripts and set the last modified header,
and user can get the cache from ServerB, C, D if cache is valid.
Otherwise, B, C, D will proxy the request to A for dynamic execution.

However, user might perform some update on the master (ServerA), and
the cache on B, C, &D will needed to be cleared manually (even not
expire).

How to do this, maybe in PHP?

Thanks.
