module: gcp_compute_target_https_proxy
description:
- Represents a TargetHttpsProxy resource, which is used by one or more global forwarding
  rule to route incoming HTTPS requests to a URL map.
short_description: Creates a GCP TargetHttpsProxy
version_added: '2.6'
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0

  name:
    description:
    - Name of the resource. Provided by the client when the resource is created. The
      name must be 1-63 characters long, and comply with RFC1035. Specifically, the
      name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?`
      which means the first character must be a lowercase letter, and all following

    - Specifies the QUIC override policy for this resource. This determines whether
      the load balancer will attempt to negotiate QUIC with clients or not. Can specify
      one of NONE, ENABLE, or DISABLE. If NONE is specified, uses the QUIC policy
      with no user overrides, which is equivalent to DISABLE. Not specifying this
      field is equivalent to specifying NONE.
