mw_range_parser {webfakes}

Middleware to parse a Range header

Description

Adds the requested ranges to the ranges element of the request object. request$ranges is a data frame with two columns, from and to. Each row corresponds one requested interval.

Usage

mw_range_parser()

Details

When the last n bytes of the file are requested, the matrix row is set to c(0, -n). When all bytes after a p position are requested, the matrix row is set to c(p, Inf).

If the intervals overlap, then ranges is not set, i.e. the Range header is ignored.

If its syntax is invalid or the unit is not bytes, then the Range header is ignored.

Value

Handler function.
