Detailed Description

A simple wrapper around another fetcher that adds headers to requests based on settings in the rewrite options before passing them on to the backend fetcher.

Member Function Documentation

virtual void net_instaweb::AddHeadersFetcher::Fetch ( const GoogleString &  url, MessageHandler *  message_handler, AsyncFetch *  fetch  )

virtual

Asynchronously fetch a URL, set the response headers and stream the contents to fetch and call fetch->Done() when the fetch finishes.

There is an unchecked contract that response_headers are set before the response_writer or callback are used. Caution, several implementations do not satisfy this contract (but should).

Todo:

TODO(sligocki): GoogleString -> GoogleUrl or at least StringPiece.

TODO(sligocki): Include the URL in the fetch, like the request headers.

Implements net_instaweb::UrlAsyncFetcher.

virtual bool net_instaweb::AddHeadersFetcher::SupportsHttps ( ) const

inlinevirtual

Determine if the fetcher supports fetching using HTTPS. By default we assume a fetcher can.

Reimplemented from net_instaweb::UrlAsyncFetcher.
