Functions

func NegotiateContentEncoding

func NegotiateContentEncoding(h http.Header, offers []string) string

NegotiateContentEncoding returns the best offered content encoding for the request's Accept-Encoding header. If two offers match with equal weight and then the offer earlier in the list is preferred. If no offers are acceptable, then "" is returned.

func NegotiateContentType

func NegotiateContentType(h http.Header, offers []string, defaultOffer string) string

NegotiateContentType returns the best offered content type for the request's Accept header. If two offers match with equal weight, then the more specific offer is preferred. For example, text/* trumps */*. If two offers match with equal weight and specificity, then the offer earlier in the list is preferred. If no offers match, then defaultOffer is returned.
