Redirect Action Result

Redirect Action Result : This redirect pattern is supported by Struts 2. The ActionMapper provided by the ActionMapperFactory is used to redirect the browser to a URL that invokes the specified action. You can see a simple implementation of this in the following struts 2 application.?

Redirects Dynamic Parameters: The action-redirect result takes following parameters:

• actionName
• namespace
• method
• encode
• parse
• location
