parseLinkHeader(linkHeader : String) : Object
Parses the given link header containing web links and returns an object keyed by
the rel property that contains information about each link.
To avoid redundantly parsing of extremely long (invalid) input, the package uses 2 env variabes:
PARSE_LINK_HEADER_MAXLEN - Sets the number of characters the input should be limited to - longer inputs will not be handled. Defaults to 2000.
PARSE_LINK_HEADER_THROW_ON_MAXLEN_EXCEEDED - Defines behavior for when the PARSE_LINK_HEADER_MAXLEN parameter is exceeded. if defined, an error will be thrown; if it's null, the function fails silently by returning null. Defaults to null`.
The purpose of this module is to parse the link header information. To format an object generated by this module back to the link header string, use the format-link-header module.
