Member Function Documentation

virtual bool net_instaweb::DataUrlInputResource::IsValidAndCacheable ( ) const

virtual

Checks if the contents are loaded and valid and also if the resource is up-to-date and cacheable by a proxy like us.

Reimplemented from net_instaweb::Resource.

virtual void net_instaweb::DataUrlInputResource::LoadAndCallback	(	NotCacheablePolicy	not_cacheable_policy,
		const RequestContextPtr &	request_context,
		AsyncCallback *	callback
	)

protectedvirtual

Load the resource asynchronously, storing ResponseHeaders and contents in object. Calls 'callback' when finished. The ResourcePtr used to construct 'callback' must be the same as the resource used to invoke this method.

Setting not_cacheable_policy to kLoadEvenIfNotCacheable will permit it to consider loading to be successful on Cache-Control:private and Cache-Control:no-cache resources. It should not affect /whether/ the callback gets involved, only whether it gets true or false.

Implements net_instaweb::Resource.

static ResourcePtr net_instaweb::DataUrlInputResource::Make	(	const StringPiece &	url,
		const RewriteDriver *	driver
	)

inlinestatic

We expose a factory; parse failure returns NULL.

We create the local copy of the url early, because encoded_contents will in general be a substring of this local copy and must have the same lifetime.

virtual bool net_instaweb::DataUrlInputResource::UseHttpCache ( ) const

inlinevirtual

Returns whether this type of resource should use the HTTP Cache. This method is based on properties of the class, not the resource itself, and helps short-circuit pointless cache lookups for file-based and data URLs.

Implements net_instaweb::Resource.

The documentation for this class was generated from the following file:
