Sophisticated servers may wish to defer the choice of the Body template type until after the header is available. Then, a body type may be chosen depending on the header contents. For example, depending on the verb, target path, or target query parameters. To accomplish this, a parser is declared to read in the header only, using a trivial body type such as [link beast.ref.boost__beast__http__empty_body `empty_body`]. Then, a new parser is constructed from this existing parser where the body type is conditionally determined by information from the header or elsewhere.
