module: bigip_profile_http
short_description: Manage HTTP profiles on a BIG-IP
description:
- Manage HTTP profiles on a BIG-IP.
version_added: 2.7
options:
name:
description:
- Specifies the name of the profile.
required: True
parent:
description:
- Specifies the profile from which this profile inherits settings.
- When creating a new profile, if this parameter is not specified, the default
is the system-supplied C(http) profile.
default: /Common/http
description:
description:
- Description of the profile.
proxy_type:
description:
- Specifies the proxy mode for the profile.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
choices:
- reverse
- transparent
- explicit
dns_resolver:
description:
- Specifies the name of a configured DNS resolver, this option is mandatory when C(proxy_type)
is set to C(explicit).
- Format of the name can be either be prepended by partition (C(/Common/foo)), or specified
just as an object name (C(foo)).
- To remove the entry a value of C(none) or C('') can be set, however the profile C(proxy_type)
must not be set as C(explicit).
insert_xforwarded_for:
description:
- When specified system inserts an X-Forwarded-For header in an HTTP request
with the client IP address, to use with connection pooling.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
type: bool
redirect_rewrite:
description:
- Specifies whether the system rewrites the URIs that are part of HTTP
redirect (3XX) responses.
- When set to C(none) the system will not rewrite the URI in any
HTTP redirect responses.
- When set to C(all) the system rewrites the URI in all HTTP redirect responses.
- When set to C(matching) the system rewrites the URI in any
HTTP redirect responses that match the request URI.
- When set to C(nodes) if the URI contains a node IP address instead of a host name,
the system changes it to the virtual server address.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
choices:
- none
- all
- matching
- nodes
encrypt_cookies:
description:
- Cookie names for the system to encrypt.
- To remove the entry completely a value of C(none) or C('') should be set.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
type: list
encrypt_cookie_secret:
description:
- Passphrase for cookie encryption.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
update_password:
description:
- C(always) will update passwords if the C(encrypt_cookie_secret) is specified.
- C(on_create) will only set the password for newly created profiles.
default: always
choices:
- always
- on_create
header_erase:
description:
- The name of a header, in an HTTP request, which the system removes from request.
- To remove the entry completely a value of C(none) or C('') should be set.
- The format of the header must be in C(KEY:VALUE) format, otherwise error is raised.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
version_added: 2.8
header_insert:
description:
- A string that the system inserts as a header in an HTTP request.
- To remove the entry completely a value of C(none) or C('') should be set.
- The format of the header must be in C(KEY:VALUE) format, otherwise error is raised.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
version_added: 2.8
server_agent_name:
description:
- Specifies the string used as the server name in traffic generated by LTM.
- To remove the entry completely a value of C(none) or C('') should be set.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
version_added: 2.8
include_subdomains:
description:
- When set to C(yes), applies the HSTS policy to the HSTS host and its sub-domains.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
type: bool
version_added: 2.8
maximum_age:
description:
- Specifies the maximum length of time, in seconds, that HSTS functionality
requests that clients only use HTTPS to connect to the current host and
any sub-domains of the current host's domain name.
- The accepted value range is C(0 - 4294967295) seconds, a value of C(0) seconds
re-enables plaintext HTTP access, while specifying C(indefinite) will set it to the maximum value.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
version_added: 2.8
hsts_mode:
description:
- When set to C(yes), enables the HSTS settings.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
type: bool
version_added: 2.8
partition:
description:
- Device partition to manage resources on.
default: Common
state:
description:
- When C(present), ensures that the profile exists.
- When C(absent), ensures the profile is removed.
default: present
choices:
- present
- absent
