Ian,
I assume this would be a pid file?
If so then what you are probably looking for is a filename_trans rule and will
require a new interface in squid.if for this.
Try something like
interface(`squid_filetrans_named_content',`
gen_require(`
type_squid_var_run_t;
')
files_pid_filetrans($1, squid_var_run_t, dir, "squozy")
')

We got you covered!
