# <netui:rewriteURL> Tag

Allows a tag name, typically either an id or name attribute, to participate in URL rewritting.

## Syntax

<netui:rewriteURL
[URL="string_url"] />

## Description

Allows a tag name, typically either an id or name attribute, to participate in URL rewritting. Some containers such as WebLogic Portal rewrite names so they are unique.

## Attributes

URL | The value of the URL that will be rewritten.
Required | Supports runtime expression evaluation | Data bindable
No | No | No

## Sample

In this sample, the id attribute of a <span> tag is set to 'foo'. The actual value that will be written to the rendered HTML may change depending on the application container. (Portal containers sometimes rewrite the id attributes to ensure their uniqueness.) The value 'foo' can be passed to `getNetuiTagName( tagId, tag )` to find the value of the id attribute actually rendered in the browser.

        <span id="<netui:rewriteURL URL="foo"/>">
