Hi All, We are using acl helper to authenticate users. Squid allows a template file that will be used to send a custom error message when the ACL sends an "ERR" string back to squid. In our case the acl helper contacts another web service for authentication. Is there a way to send the message we get from the web service (or any thing that changes from request to request) back to the client. Essentially what we are looking for is a way to change the error message at run time. thanks for any help, Sreenath _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
