+
+
+## Syntax
+A `google_compute_target_http_proxies` is used to test a Google TargetHttpProxy resource
+
+## Examples
+```
+describe google_compute_target_http_proxies(project: 'chef-gcp-inspec') do
+  its('names') { should include 'inspec-gcp-http-proxy' }
+  its('descriptions') { should include 'A HTTP proxy' }
+end
+```
+
+## Properties
+Properties that can be accessed from the `google_compute_target_http_proxies` resource:
+
+See [google_compute_target_http_proxy.md](google_compute_target_http_proxy.md) for more detailed information
+  * `creation_timestamps`: an array of `google_compute_target_http_proxy` creation_timestamp
+  * `descriptions`: an array of `google_compute_target_http_proxy` description
+  * `ids`: an array of `google_compute_target_http_proxy` id
+  * `names`: an array of `google_compute_target_http_proxy` name
+  * `url_maps`: an array of `google_compute_target_http_proxy` url_map
+
+## Filter Criteria
+This resource supports all of the above properties as filter criteria, which can be used
+with `where` as a block or a method.

+
+## Properties
+Properties that can be accessed from the `google_compute_target_http_proxy` resource:
+
+  * `creation_timestamp`: Creation timestamp in RFC3339 text format.
+
+  * `description`: An optional description of this resource.
+
+  * `id`: The unique identifier for the resource.
+
+  * `name`: 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 characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
+
+  * `url_map`: A reference to the UrlMap resource that defines the mapping from URL to the BackendService.
