Hello All
Whether ttl=50 （value) is too low , Maybe i will update ttl value to
ttl=3600 cache=1048576 .
i have a question still , Whether cached results for external_acl is
reponse from helper program ?
for example :
if FORMAT is %SRC , and helper progrm return "OK\n" ,
and external_acl_type tell squid to cache suitable %SRC ( for example :
client is 192.168.0.21 ,and will cache 192.168.0.21 into Cache valued )
if helper progrm return "ERR\n" ,
won't cache any value or cache src ip into cached negative valued ...
Whether My understanding is correct ?
external_acl_type name [options] FORMAT.. /path/to/helper [helper
arguments..]
Options:
ttl=n TTL in seconds for cached results (defaults to 3600
for 1 hour)
negative_ttl=n
TTL for cached negative lookups (default same
as ttl)
cache=n Limit the result cache size, default is 262144.
The expanded FORMAT value is used as the cache key, so
if the details in FORMAT are highly variable a larger
cache may be needed to produce reduction in helper load.

Hello All:
i test splash portal via external_acl_type ...
Although the first people succeed to login and can access internet , but
when second people succeed to login and can access internet ,
and the firest people have to login again . when the firest people
succeed to login and can access internet ,
second people have to login again .
my meaning is : There's only one person who can access internet at same
time
I guess [channel-ID] is error at my config , but i can't confirm.
if concurrency=10
how to identify or find correct [channel-ID] ,
and
Whether return value format is correct for squid ?
for example
fwrite(STDOUT, $stream_id." ERR\n");
If possible , please give me some advisement .
