Blue Coat Systems Time Clock Proxy SG Manuel D’Utilisation
Appendix C:
Recognized HTTP Headers
The tables provided in this appendix list all recognized HTTP 1.1 headers and indicate how the
ProxySG is able to interact with them. For each header, columns show whether the header appears in
request or response forms, and whether the
ProxySG is able to interact with them. For each header, columns show whether the header appears in
request or response forms, and whether the
append( )
,
delete( )
,
rewrite( )
, or
set( )
actions
can be used to change the header.
Recognized headers can be used with the
request.header.header_name=
and
response.header.header_name=
conditions. Headers not shown in these tables must be tested with
the
request.x_header.header_name=
and
response.x_header.header_name=
conditions. In
addition, the following three header fields take address values, so they can be used with the condition
request.header.header_name.address= Client-IP, Host, X-Forwarded-For.
