Abstract

Official abstract text for this publication.

A web client is controlled to actively ignore scripts in certain portions of a web document using control instructions in the form of a special pair of markup language “tags.” A tag pair of this type is defined by a first tag, and a second tag paired with the first tag to form the tag pair. Each of the first and second tags includes a same identifier, and the tag pair is adapted to be recognized by a browser interpreter to instruct the web client to ignore given information located with the tag pair. Thus, when a web document is received by a web client, it is parsed (by the interpreter) in the usual manner. Upon determining that the tag pair is present, the browser bypasses (ignores) given information (typically, a script) located with the tag pair. Bypassing the script reduces the possibility that the script can be used for malicious purposes, such as an XSS attack.
