Flags
Flag Description
Abort server
By default, when a client closes a connection, Equalizerwaits for a response from
the server before closing the server connection. If this flag is enabled, Equalizer
will not wait for a response before closing the connection to the server; instead it
sends a TCP RST (reset) to the server when the client closes the connection.
This option will typically reduce the number of server connections in the TIME_
WAIT state, as shown by the netstat console command.
Insert client IP
When this flag is enabled, Equalizer inserts an X-forwarded-for: header with the
client's IP address into all client requests before they are sent to the server. This
flag is disabled by default for HTTP clusters and enabled by default for HTTPS
clusters.
TCP Multiplexing
This selection enables TCP multiplexing for a cluster. TCP multiplexing must also
be enabled on at least one server instance in the server pool assigned to the
cluster (or one of its match rules).
Allow Multibyte Characters
By default, support for extended characters (8-bit ASCII and multibyte UTF char-
acters) in URIs is disabled. Equalizer returns a 400 Bad Request error when a
request URI contains 8-bit or multibyte characters. To enable support for 8-bit
and multibyte characters in URIs, click this checkbox. There are potential risks
to enabling this option, because it allows Equalizer to pass requests that violate
RFC2396; load-balanced servers may be running software that is incapable of
handling such requests. Therefore, ensure that your server software is capable
of handling URIs containing extended characters and will not serve as a potential
weak point in your network before you enable extended characters.
Compress (Not applicable to
E250GX)
When this option is enabled, Equalizer automatically detects requests to the
cluster from compression-capable browser clients and performs GZIP com-
pression on all cluster responses sent to that client. This disable - Disable this
cluster. The cluster IP address will not accept requests when this flag is
enabled.
Once only
Limits Equalizer to parsing headers (and executing match rules) for only the
first request of any client making multiple requests across a single TCP con-
nection. This option is off by default: meaning that Equalizer will parse the head-
ers of every client request.
Rewrite Redirects
When enabled, forces Equalizer to pass responses from an HTTPS cluster’s serv-
ers without rewriting them. In the typical Equalizer setup, you configure servers
in an HTTPS cluster to listen and respond using HTTP; Equalizer communicates
with the clients using SSL. If a server sends an HTTP redirect using the Loca-
tion: header, this URL most likely will not include the https: protocol. Equalizer
rewrites responses from the server so that they are HTTPS. You can direct Equal-
izer to pass responses from the server without rewriting them by enabling this
option.
Ignore case
Applies to L7 clusters and is the global setting to ignore case in match expres-
sions. You can override this value per cluster and per match rule .
