Application server cluster mapping settings You
can configure settings for an application server cluster
mapping. Application server cluster mappings are specified only for
an application server cluster custom advisor.
Caching action settings You can configure
caching action settings for a proxy server.
Caching actions are set to determine whether a response is cached.
A caching action specifies the last modified factor and the default
expiration to define how a response is cached.
Creating a proxy cluster: Create additional proxy cluster members Use this page to create additional members for a proxy
cluster.
You can add a member to a proxy cluster when you create the proxy
cluster
or after you create the proxy cluster. A copy of the first proxy cluster
member
that you create is stored as part of the proxy cluster data and becomes
the
template for all additional proxy cluster members that you create.
Custom advisor policy settings You can configure
settings for a custom advisor policy.
Custom advisor policies allow for more specific determination of target
application server availability by sending protocol level requests
to back-end servers. Custom advisor policies are unique based on the
combination of the business-level application ID and the composition
unit ID.
Custom
advisors collection Use this page to administer
custom adviser policies.
With custom advisors, you can determine the availability of a specific
target
application server by sending protocol level requests to back-end
servers.
Custom advisor policies are unique based on the combination of the
business-level
application ID and the composition unit ID.
Denial of service protection settings Use these settings to define denial of service protection
for the proxy server. The buffer chunk sizes are used to provide protection
against denial of service attacks. It is very important to tune these
settings to balance the level of protection with the performance impacts
that can be experienced.
Generic server cluster mapping settings You
can configure settings for a generic server cluster
mapping. Generic server cluster mappings are specified only for a
generic server cluster custom advisor.
Generic server cluster members After defining
the generic server cluster name, use this page to
define the members of the cluster.
Generic server cluster ports collection After
defining the generic server cluster name, use this page to
create, delete, and configure the members of the cluster.
Generic server cluster route action settings You can configure a generic server cluster route action
for a proxy server. Add a generic server cluster route action to define
routes for inbound requests to specific generic server clusters.
Generic server clusters collection Use this
page to create, delete or modify a generic server
cluster. Creating a generic server cluster is the next step towards
generating the ability to route requests to a non-IBM application
server, after creating the proxy server.
Generic
server clusters configuration Use this topic to
configure a generic server cluster. Creating
a generic server cluster is the next step, after creating the proxy
server, towards generating the ability to route requests to a non-IBM
application server.
HTTP compression action settings You can
configure settings for an HTTP request compression action
or an HTTP response compression action for a proxy server. Compression
actions
are set to compress the request message to the server or response
message
to the client.
HTTP header action settings You
can configure settings for an HTTP request header action
or an HTTP response header action for a proxy server. Use header modification
actions to add, modify, or delete request and response headers.
Proxy actions collection Use this page to administer actions for the proxy server.
Proxy actions include creating, modifying, or deleting rules that
affect caching, compression, headers, rewriting, and routing for the
proxy server. The Proxy actions collection panel allows you to configure
proxy actions from one interface.
Proxy cluster member settings Use this page to manage the members of a proxy cluster.
A proxy cluster of proxy servers is managed together and participate
in workload management.
Proxy rule expression settings You can configure settings for a proxy rule expression.
A proxy rule expression consists of operands and operators that are
defined by an administrator. If a proxy rule expression evaluates
to true, then all proxy actions configured for that rule expression
are run.
Proxy rule expressions collection Use this page to administer proxy rule expressions for
the proxy server. Proxy rule expressions allow you to make configuration
rules more granular in scope by specifying information within the
rule. A proxy rule expression is associated with a virtual proxy host
and consists of operands and operators that are defined by an administrator.
When an expression evaluates to true, the proxy action rules associated
with that proxy rule expression are performed.
Proxy server cluster collection Use this page to view information about and change configuration
settings for a proxy server cluster. A proxy cluster consists of a
group of proxy servers.
Proxy server cluster settings Use this page to view a list of the proxy server clusters
that are defined for your system, and the status of each of these
clusters. You can also use this page to view or change the configuration
settings for a specific proxy server cluster or to view the local
topology of a specific proxy server cluster.
Proxy server collection This topic lists the proxy servers in the cell. A proxy
server resides within a node.
Proxy server configuration You can modify an existing proxy server to perform advanced
routing options, such as routing requests to a non-WebSphere Application Server cell, and to perform
caching. The options to configure the proxy server from this panel
are under Proxy server properties.
Proxy server settings Use this topic to perform advanced configuration on a proxy
server. Proxy settings enable the system administrator to fine tune
the behavior of the proxy server. In particular, you can configure
the connections and requests to the application server, enable caching,
configure the requests that must be rejected, define how error responses
are handled, and specify the location of the proxy logs.
Proxy virtual host settings You can configure
settings for a proxy virtual host. A
proxy virtual host allows a single proxy server to host multiple domains
or ports on a single IP or port. Each proxy virtual host consists
of a domain name and a port.
Proxy virtual host settings details Use this panel to override some proxy server scoped settings
with values to be used for the proxy virtual host.
Proxy
virtual hosts collection Use this page to administer
proxy virtual hosts. A proxy virtual
host allows a single proxy server to host multiple domains or ports
on a single
IP or port. Each proxy virtual host consists of a domain name and
a port.
Rewrite action settings You can configure settings to implement a rewrite action
for outbound responses handled by the proxy server. Rewriting actions
define how the proxy server rewrites elements of the uniform resource
locators, such as URLs in an HTML page or the redirect link in the
response. Rewrite actions are often done to mask the back-end server
identity with that of the proxy server.
Rewriting
rules configuration Rewriting rules define how the
proxy server rewrites URLs.
Responses that have been redirected by target servers typically return
a 302 status code with a location header that defines the URL that
the client should be redirected to. Rewriting this URL is necessary
if the target server is not aware of the proxy servers. The redirected
URL is modified to correctly point clients to the proxy server instead
of directly to a target server that may not be visible to clients.
Use the following properties to configure the URL rewriting rules
for a proxy server
Route action settings You can configure settings for a route action for a proxy
server. Add a route action to define routes to local file system resources
for static file serving.
Routing rules Use this topic to set the advanced
configuration routing
rules to ensure work requests arrive at the proper generic server
cluster. From this topic you can create, delete, or modify a routing
rule.
Routing
rules configuration Use this topic to create the
advanced configuration routing rules
to ensure that work requests arrive at the proper generic server cluster.
Stand-alone application server cluster mapping
settings You can configure settings for a stand-alone
application
server cluster mapping. Stand-alone application server cluster mappings
are specified only for a stand-alone application server cluster custom
advisor.
Static
cache rule settings Use this topic to configure
a cache rule that is associated to
a URI group for the proxy server. HTTP 1.1 defines a set of rules
for proxy
servers to cache content. Static cache rules enable these default
rules to
be overridden for a given address space. Before the rules have any
meaning,
you must enable caching on the Servers >
Server
Types > WebSphere proxy servers > proxy_server_name > HTTP Proxy Server Settings > Proxy settings administrative console page.
Static cache rules collection This topic
lists the static cache rules for a proxy server. From
this topic you can create, delete, or modify a static cache rule.
Time mapping settings You can configure time
mapping settings for the proxy server that
set routing rules to be in effect during specific time intervals.
These settings
can be specified for application server members or for generic server
cluster
members.
URI
group configuration Use this topic to configure
a URI group that can be mapped back
to generic server clusters. When creating a URI group, ensure that
you are
planning for URIs that form a logical collection.
URI groups A group of URI patterns, which
you define, that can be mapped back
to generic server clusters. When creating a URI group, verify that
you are
planning for URIs that form a logical collection. From this topic,
you can
create, delete, or modify a URI group.
