Purpose
• put—Matches HTTP packets with the PUT method
[0x50555420]
• trace—Matches HTTP packets with the TRACE
method [0x54524143]
The tcp-option-length option specifies the length of the
TCP options header in the packets. You can configure up
to four TCP option lengths (in multiples of four bytes) in
the access control entries (ACEs). The length range is from
0 to 40. If you do not configure this option, the length is
specified as 0, and only packets without the TCP options
header can match the ACE. This option allows the HTTP
method to be matched even on packets that have a
variable-length TCP options header.
The redirect option redirects an HTTP method to a server
that is connected to a specific port. The HTTP redirect
feature does not work on Layer 3 ports.
