#
# URL Remapping Config File
#
# Using remap.config allows you to accomplish two things:
#
# 1) Rewrite a URL (from the client) before sending it to the Origin Server.
# 2) Protect the proxy server, to only allow certain requests.
#
# With the default configurations, at least one remap rule is required. This
# can be relaxed with the following configuration in records.config:
#
# CONFIG proxy.config.url_remap.remap_required INT 0
#
# Be aware, doing so makes the proxy a generic, open-relay!
#
# The format is:
# <map_type> client-URL origin-server-URL <tag_value> <filtering>
#
# Where client-URL and origin-server-URL are both of the format
# <scheme>://<host>:<port>/<path_prefix>
#
# The <tag_value> directive is optional and can be different for different
# types of <map_type>. The <filtering arguments> are optional ACL-like
# arguments unique for each remap rule
#
# Six different types of mappings are possible:
# map
# map_with_referer
# map_with_recv_port
# reverse_map
# redirect
# redirect_temporary
#
# Each of these map types can be prefixed with the string 'regex_' to indicate
# that the rule will have regular expression strings. See the last part of
# this description for more information on regex support.
#
# The 'map' mapping is the most straightforward. Requests that match the
# client-URL are rewritten into the origin-server-URL. The user agent will see
# the page on the remapped URL, but will not be notified of the address
# change.
#
# The 'map_with_referer' is an extended version of 'map', which can be used to
# activate the so-called "deep linking protection" feature available in
# Apache Traffic Server.
#
# The 'map_with_recv_port' is exactly like 'map' except that it uses the port
# at which the request was received to perform the mapping instead of the port
# present in the request. When present, 'map_with_recv_port' mappings are
# checked first. If there is a match, then it is chosen without evaluating the
# "regular" forward mapping rules.
#
# The 'reverse_map' mapping is used to rewrite location headers sent by the
# origin server. The 'redirect' mapping creates a permanent redirect message
# and informs the browser of the URL change.
#
# The 'redirect_temporary' mapping acts in the same way but tells the browser
# that this redirect is only temporary. We need to map the URL in reverse
# proxy mode so that user agents know to contact Traffic Server and not
# attempt to contact the Origin Server directly.
#
# For example, you can set up a reverse proxy for www.example.com with the
# real content situated at server1.example.com with the rules:
#
# map http://www.example.com/ http://server1.example.com/
# reverse_map http://server1.example.com/ http://www.example.com/
#
# Or you could permanently redirect users trying to access www.oldserver.com
# to www.newserver.com with the following rule:
#
# redirect http://www.oldserver.com/ http://www.newserver.com
#
# If the redirect is only temporary, you want to only temporarily remap the
# URL. You could use the following rule to divert users away from a failed
# server:
#
# redirect_temporary http://broken.firm.com http://working.firm.com
#
# In order to use "deep linking protection" Traffic Server's feature, the
# 'map_with_referer' mapping scheme must be used. In general, the format of is
# the following:
#
# map_with_referer client-URL origin-server-URL redirect-URL regex1 [regex2 ...]
#
# 'redirect-URL' is a redirection URL specified according to RFC 2616 and can
# contain special formatting instructions for run-time modifications of the
# resulting redirection URL. All regexes Perl compatible regular expressions,
# which describes the content of the "Referer" header which must be
# verified. In case an actual request does not have "Referer" header or it
# does not match with referer regular expression, the HTTP request will be
# redirected to 'redirect-URL'.
#
# At least one regular expressions must be specified in order to activate
# 'deep linking protection'. There are limitations for the number of referer
# regular expression strings - 2048. In order to enable the 'deep linking
# protection' feature in Traffic Server, configure records.config with:
#
# CONFIG proxy.config.http.referer_filter INT 1
#
# In order to enable run-time formatting for redirect0URL, configure
#
# CONFIG proxy.config.http.referer_format_redirect INT 1
#
# When run-time formatting for redirect-URL was enabled the following format
# symbols can be used:
#
# %r - to substitute original "Referer" header string
# %f - to substitute client-URL from 'map_with_referer' record
# %t - to substitute origin-server-URL from 'map_with_referer' record
# %o - to substitute request URL to origin server, which was created a
# the result of a mapping operation
#
# Note: There is a special referer type "~*" that can be used in order to
# specify that the Referer header is optional in the request. If "~*" referer
# was used in map_with_referer mapping, only requests with Referer header will
# be verified for validity. If the "~" symbol was specified before referer
# regular expression, it means that the request with a matching referer header
# will be redirected to redirectURL. It can be used to create a so-called
# negative referer list. If "*" was used as a referer regular expression -
# all referers are allowed. Various combinations of "*" and "~" in a referer
# list can be used to create different filtering rules.
#
# Examples:
# map_with_referer http://y.foo.bar.com/x/yy/ http://foo.bar.com/x/yy/ http://games.bar.com/new_games .*\.bar\.com www.bar-friends.com
#
# Explanation: Referer header must be in the request, only ".*\.bar\.com"
# and "www.bar-friends.com" are allowed.
#
# map_with_referer http://y.foo.bar.com/x/yy/ http://foo.bar.com/x/yy/ http://games.bar.com/new_games * ~.*\.evil\.com
#
# Explanation: Referer header must be in the request but all referers are
# allowed except ".*\.evil\.com".
#
# map_with_referer http://y.foo.bar.com/x/yy/ http://foo.bar.com/x/yy/ http://games.bar.com/error ~* * ~.*\.evil\.com
#
# Explanation: Referer header is optional. However, if Referer header exists,
# only request from ".*\.evil\.com" will be redirected to redirect-URL.
#
# There are optional filtering arguments that can be specified at the end of the mapping definition line:
#
# @action=allow|deny
# @src_ip=IP-address
# @method=HTTP method string (CONNECT|DELETE|GET|HEAD|ICP_QUERY|OPTIONS|POST|PURGE|PUT|TRACE|PUSH)
# @plugin=<plugin_path>
# @pparam=<plugin_param>
#
# There is no limitation for the number of filtering arguments.
#
# Example:
# map http://foo.cow.com/ http://bar.cow.com @src_ip=10.72.118.51-10.72.118.62 @method=GET @method=DELETE @src_ip=192.168.0.1-192.168.0.254 @action=allow @method=PUT
#
# Traffic Server supports WebSockets but it must be enabled via remap. WebSocket upgrades are automatically
# detected when there exists a remap rule containing a ws:// scheme.
#
# Example:
# map ws://bar.com/ ws://foo.com/
#
# Explaination: When a request comes in with the appropriate upgrade headers, Traffic Server will use this
# remap rule in an attempt to establish and maintain a websocket connection.
#
# Named filters can be created and applied to blocks of mappings
# using the .definefilter, .activatefilter, and .deactivatefilter
# directives. Named filters must be defined using .definefilter
# before being used. Once defined, .activatefilter can used to
# activate a filter for all mappings that follow until deactivated
# with .deactivatefilter.
#
# Example:
# .definefilter disable_delete_purge @action=deny @method=delete @method=purge
# .definefilter internal_only @action=allow @src_ip=192.168.0.1-192.168.0.254 @src_ip=10.0.0.1-10.0.0.254
#
# .activatefilter disable_delete_purge
#
# map http://foo.example.com/ http://bar.example.com/
#
# .activatefilter internal_only
# map http://www.example.com/admin http://internal.example.com/admin
# .deactivatefilter internal_only
#
# map http://www.example.com/ http://internal.example.com/
#
#
# Regex support: Regular expressions can be specified in the rules with the
# following limitations:
#
# 1) Only the host field can have regexes - the scheme, port and other
# fields cannot.
# 2) The number of capturing sub-patterns is limited to 9;
# this means $0 through $9 can be used as substitution place holders ($0
# will be the entire input string)
# 3) The number of substitutions in the expansion string is limited to 10.
