Policy rules

Policy rules define handling rules for outbound HTTP connections. Policy rules are identified by a URL pattern. When an outbound HTTP connection is opened, the portal compares the URL of that outbound HTTP connection against the URL pattern of the policy rule and handles the URL accordingly.

A policy rule contains the following settings:

URL pattern:

Policy rules are identified by their URL patterns. If an outbound HTTP connection to a certain URL is connected, the outbound HTTP connection service checks the URL patterns of all policy rule items in the accessible policy mappings. The policy rule with the URL pattern that matches best is selected.

basicAuth

If true, connection is protected by basic authentication. If false, connection is not protected by basic authentication.

active

Whether this rule is active or not.

Set of allowed methods:

Restricts HTTP methods for the URL connection. For example, if specified Get, Post as the set of allowed methods, then only GET and POST requests are permitted for the URLs that this policy rule controls. If a policy rule does not contain a list of allowed methods, then all HTTP methods are permitted.

Set of mime types:

Restricts the allowed mime type of the content received. For example, if specified the set text/html, text/plain, it restricts outbound HTTP connections to content that is either plain text or HTML output. If we specify no list of supported mime types, then outbound HTTP connections are not restricted to certain mime types.

A set of Headers:

A policy rule can restrict the outbound connection to a set of request headers allowed for the remote connection.

A custom chain of URL connection filters:

To add an outbound HTTP connection that provides custom function, we can add a chain of custom URL connection filters. The outbound HTTP connection service provides a filter API. Programmers can use this API to write filters called whenever an outbound HTTP connection is opened. For more information, read Program extensions for outbound HTTP connections.
