* no-op commit due to failed cherry-picking * [NET-4897] net/http host header is now verified and request.host that contains socked now error (#18129) ### Description This is related to https://github.com/hashicorp/consul/pull/18124 where we pinned the go versions in CI to 1.20.5 and 1.19.10. go 1.20.6 and 1.19.11 now validate request host headers for validity, including the hostname cannot be prefixed with slashes. For local communications (npipe://, unix://), the hostname is not used, but we need valid and meaningful hostname. Prior versions go Go would clean the host header, and strip slashes in the process, but go1.20.6 and go1.19.11 no longer do, and reject the host header. Around the community we are seeing that others are intercepting the req.host and if it starts with a slash or ends with .sock, they changing the host to localhost or another dummy value.

Consul
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh - Consul Service Mesh enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections with Transparent Proxy.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, macOS, FreeBSD, Solaris, and Windows and includes an optional browser based UI. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
