# This class is part of the Gitlab::HTTP wrapper. It handles local requests and header timeouts
|
|
#
|
|
# 1. Local requests
|
|
# Depending on the value of the global setting allow_local_requests_from_web_hooks_and_services,
|
|
# this adapter will allow/block connection to internal IPs and/or urls.
|
|
#
|
|
# This functionality can be overridden by providing the setting the option
|
|
# allow_local_requests = true in the request. For example:
|
|
# Gitlab::HTTP.get('http://www.gitlab.com', allow_local_requests: true)
|
|
#
|
|
# This option will take precedence over the global setting.
|
|
#
|
|
# 2. Header timeouts
|
|
# When the use_read_total_timeout option is used, that means the receiver
|
|
# of the HTTP request cannot be trusted. Gitlab::BufferedIo will be used,
|
|
# to read header data. It is a modified version of Net::BufferedIO that
|
|
# raises a timeout error if reading header data takes too much time.
