Blue Coat Systems Proxy SG manual Appendix C Recognized Http Headers

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 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.
