Detailed Description

A URL partnership should be established in order to combine resources, such as in CSS combination, JS combination, or image spriting. This class centralizes the handling of such combinations, answering two questions:

1. Is it legal for a new URL to enter into the partnership
2. What is the greatest common prefix
3. What are the unique suffices for the elements.

Member Function Documentation

bool net_instaweb::UrlPartnership::AddUrl	(	const StringPiece &	resource_url,
		MessageHandler *	handler
	)

Adds a URL to a combination. If it can be legally added, consulting the DomainLaywer, then true is returned.

static bool net_instaweb::UrlPartnership::FindResourceDomain ( const GoogleUrl &  base_url, const UrlNamer *  url_namer, const RewriteOptions *  rewrite_options, GoogleUrl *  resource, GoogleString *  domain, MessageHandler *  handler  )

static

Based on the UrlNamer and DomainLawyer, find the domain associated with a request, removing any proxy prefix that may have been added by the UrlNamer. The meaning of "associated" is defined by the UrlNamer implementation. *resource is also adjusted to the version that will be written out to the page.

int net_instaweb::UrlPartnership::NumCommonComponents ( ) const

inline

Returns the number of common path components for all resources in this partnership.

GoogleString net_instaweb::UrlPartnership::RelativePath

(

int

index

)

const

Returns the relative path of a particular URL that was added into the partnership. This requires that Resolve() be called first.

virtual void net_instaweb::UrlPartnership::Reset ( const GoogleUrl &  original_request )

virtual

Establish a new URL as the original request, which is used for domain authorization and mapping of URLs as they are added to the partnership.

GoogleString net_instaweb::UrlPartnership::ResolvedBase

(

)

const

Computes the resolved base common to all URLs. This will always have a trailing slash.
