+icap_enable on
+icap_send_client_ip on
+icap_send_client_username on
+icap_client_username_encode off
+icap_client_username_header X-Authenticated-User
+icap_preview_enable on
+icap_preview_size 1024
+icap_service service_avi_req reqmod_precache icap://localhost:1344/squidclamav bypass=off

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
