This is same as link tag .The rewrite tag is used to generate a URI based on exactly same rules as the link tag. But it defers without creating the <a> hyperlink. This tag is used when we want to create URI as string constants in JavaScript code.

There are four ways to specify the base URL:-
  • The action attribute :- This contains the actual content relative URI of the destination of this transfer.
  •  You must specify exactly one of the action attribute, the forward attribute, the href attribute, or the page attribute  
  • The forward attribute :-This is identified the name of the global forward element that received control these request. 
  • The href attribute :-This attributes is used to forward the current request.
  • The page attribute :-It specifies an application relative path  which this hyperlink will transfer control if activated.  Example The href attribute to specify an absolute URL for the frame: The page attribute to specify an absolute URL for the frame:

<%taglib uri="http://struts.apache.org/tags-html" prefix="html"%>

<a href="<html:rewrite action="Hello.do" />" 
This is url and click here
<html:rewrite action="Hello.do " />
</a>
