Detailed Description

This class keeps track of the request properties of the client, which are for the most part learned from the UserAgent string and specific request headers that indicate what optimizations are supported; most properties are described in device_properties.h. It relies on DeviceProperties and DownstreamCachingDirectives objects for deciding on support for a given capability.

Member Function Documentation

void net_instaweb::RequestProperties::ParseRequestHeaders ( const RequestHeaders request_headers)

Calls ParseCapabilityListFromRequestHeaders on the underlying DownstreamCachingDirectives object.

bool net_instaweb::RequestProperties::SupportsWebpInPlace ( ) const

Note that it's assumed that if the proxy cache SupportsWebp it also supports the Accept: image/webp header (since this represents a strict subset of the user agents for which SupportsWebpRewrittenUrls holds).
