 SupportNoscriptFilter (RewriteDriver *rewrite_driver)
virtual void StartDocument ()
virtual void StartElement (HtmlElement *element)
virtual const char * Name () const
 The name of this filter -- used for logging and debugging.

Detailed Description

Inserts a noscript tag as the first element of body. This noscript redirects to "ModPagespeed=off" to prevent breakage when pages rewritten by filters that depend on script execution (such as lazyload_images) are rendered on browsers with script execution disabled.


Member Function Documentation

Starts a new document. Filters should clear their state in this function, as the same Filter instance may be used for multiple HTML documents.

Reimplemented from net_instaweb::EmptyHtmlFilter.

virtual void net_instaweb::SupportNoscriptFilter::StartElement ( HtmlElement element) [virtual]

When an HTML element is encountered during parsing, each filter's StartElement method is called. The HtmlElement lives for the entire duration of the document.

Todo:
TODO(jmarantz): consider passing handles rather than pointers and reference-counting them instead to save memory on long documents.

Reimplemented from net_instaweb::EmptyHtmlFilter.
