Well to be honest m not so sure, i have seen the code at
src/redirect.cc and cant confirm the behavior m seen, but if i put a
debug line logging all input send to the redirector script i find
thousands of \n (0x0a), a good line of arguments and then another
thousands of \n (0x0a), maybe as you say this is not send by squid but
maybe something related to the way python read the stdin, don't know
but obviously as of the moment m sending a \n per every line i found
that doesn't have the well-know syntax and seems to work...
====
arguments = line.strip('.- \n').split(' ')
# Validation
if ( len(arguments) < 6 ):
sys.stdout.write( "\n" )
continue
====
The strange thing here and the thing that make ask for this behavior
is because if i don't send that "\n" and just ignore the redirector,
it does not work well, they start to die quickly and sometimes even
lag themselves, at the moment i'm considering that behavior some kind
of keep-alive related thing but not so sure so if someone here
enlighten me more about if m doing well or is a strange bug, it will
be very appreciated.

OK, will see but as of the moment m thinking in the subprocess library.
