This application was designed to give users usable data surrounding the requests being sent to their Barracuda Web Filter. The application was designed using data from a Barracuda Web Filter 310, even though the access logs should be universal across the Barracuda Web Filter family of appliances I cannot guarentee it will work with other versions.

Pre-deployment Assumptions:

1. You have enabled syslog logging on your Web Filter appliance.
2. The logs are being absorbed by Splunk and given a sourcetype name "barracuda"
3. You are using LDAP authentication. If you are not you may need to tweak the stanza named barracuda_without_ldap in transforms.conf
