View Source RemoteIp.Parsers.Generic (remote_ip v1.1.0)
Generic parser for forwarding headers.
This module implements the RemoteIp.Parser behaviour. When there is not a
more specific parser, RemoteIp.Headers.parse/1 falls back to using this
one.
The value is parsed simply as a comma-separated list of IPs. This is suitable
for a wide range of headers, such as X-Forwarded-For, X-Real-IP, and
X-Client-IP.
Any amount of whitespace is allowed before and after the commas, as well as at the beginning & end of the input.
