Allow Specifying Command or Headers for Load Balanced Web Service #2817
Description
Request
I need to explicitly set a defined HOST header so that my web service will accept the request instead of returning a 404.
- Allow setting either a
commandlike the Backend Service allows so that I can override the host header - Allow settings a
headersdict that gets included in the healthcheck request - Allow setting a
hostkey of where the request should originate from
How We Ended Up Here
We are running our application in a multi-tenant manner, where each tenant gets a separate subdomain and database schema. What this means is that specific host headers must be provided that align with one of the known tenant subdomains for a response to return 2xx. Even our global/public domain is technically a tenant, so when the healthcheck is hitting it with an unknown host header, its constantly returning a 404.
What I'm Doing Right Now
Currently I am allowing 404s to be accepted in the healthcheck, which is not ideal at all.

Edit: I was able to get around this further by using a custom middleware in my request lifecycle that just short-circuits a response if the request is going to /healthcheck so that none of the multi-tenancy code has a chance to run. I will keep this open in case its something that the project still feels like including.
