[squid-users] Squid doesn't call helper

[Kornexl, Anton]

Thank you very much

With the debug option i found the error

An external acl program  later in the config returned a number and OK in one line (5:OK or 10:ERR)
The acl handler in squid got an exception handling this returned result and all requests got DENIED

After correcting the external handler squid works OK 
AAAHHHH  

Yours 
Anton Kornexl

Please check cache.log to find out which of those two very different
things is happening.

One means the ACL is not being checked or credentials not provided. The
other means credentials are invalid.

You may need to set this directive:
  debug_options 11,2 29,5 28,4

That means the auth result was not deny.

There is no deny line in your shown config using auth ACLs.

Check cache.log with this directive set:
  debug_options 11,2 29,5 28,4

That strongly implies you have an ordering problem in your config file.
One early ACL allowing or denying traffic before any helpers get checked.

Since they are all the same type, and used the same way at the same time
You can combine all those ACLs into one name.

Please try the recommended auth config:

  http_access deny !proxyusers
  http_access allow localnet
