Proxy rule expression settings

We 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.

From the admin console, click...

An expression name must be unique and cannot contain an invalid character. The name field cannot contain the following characters: # \ /, : ; " * ? < > | = + & % '.


Expression

Expression that is evaluated when an inbound request is made to the proxy virtual host. Create expressions manually by entering the text into this field, or we can use the Subexpression builder to generate a new expression.

Specify the following settings for the Subexpression builder. Use the following operands in your expression:

Operands Description
Cell Cell containing the server to which the request is mapped.
Application Java EE application that a given request maps to on the back end server.
Module Java EE application module to which a given request is mapped.
URI The URI for an inbound request.
URIgroup Specifies a group of URIs to match against the URI. If the inbound request is in the URI group, then the expression evaluates to true.

We can configure the following proxy actions for a proxy rule expression:
