Detailed Description

This filter applies only for requests that are redirects to "?PageSpeed=noscript". It inserts a "<link rel=canonical href="URL without the query param" >" element in the head.

Todo:
TODO(sriharis): Set a cookie so that subsequent requests from the same client do not cause redirects.

Member Function Documentation

virtual void net_instaweb::HandleNoscriptRedirectFilter::StartDocument ( )
virtual

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::HandleNoscriptRedirectFilter::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.
