[FuhuXia]

User Story

In order to improve cloudfront cache hit rate, datagov team wants exlcude from_hint from the cache key in the cloudfront cache policy.

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• Run the following command a few times. You should get x-cache: Hit from cloudfront
  then change from_hint in the url string to use any some other number. You should NOT see x-cache: Miss from cloudfront

curl -Is https://catalog-beta.data.gov/dataset/inventory-of-owned-and-leased-properties-iolp?from_hint=1 | grep x-cache:

Background

[Any helpful contextual notes or links to artifacts/evidence, if needed]

Security Considerations (required)

[Any security concerns that might be implicated in the change. "None" is OK, just be explicit here!]

Sketch

This needs to be coordinated with cg support team to edit cache policy.

There's an "All-Except" choice we can use for this in configuring a Cloudfront cache policy: https://stackoverflow.com/questions/67524721/cloudfront-how-to-disable-cache-for-specific-querystrings

We'll have to figure out how to express our desired setup to Cloud.gov support. We can prototype the configuration steps in our team's AWS account to make it clear what we want.

It is easier to give them a step by step instructions on the AWS console UI. Might be too difficult to find a way to them-export, us-import, us-edit, us-export, them-import.

Most of these have been fixed but should complete precutover to improve longevity of system.
Coordinate with support

We actually use this query parameter to create the link back to search results so we can't ignore it in the cache.
