Member Function Documentation

static FetchResponseStatus net_instaweb::HttpCacheFailure::ClassifyFailure ( const ResponseHeaders &  headers, StringPiece  contents, bool  physical_fetch_success, bool  external_cacheable  )

static

Classify results of a fetch as success, or as particular kind of failure, based on fetch results (including headers and contents).

The "is this cacheable" bit is injected from external computation so this code doesn't have to worry about all the various knobs we have for overriding TTL.

Parameters

external_cacheable

e.g. what Done() said

static FetchResponseStatus net_instaweb::HttpCacheFailure::DecodeFailureCachingStatus ( HttpStatus::Code  code )

static

These two methods are used to convert between failure status classification and the magic status codes we use to remember such failures in HTTP cache.
