To invalidate an existing cache entry of a request and retrieve the latest data from the integration endpoint, one must send the request together with the Cache-Control: max-age=0 header. If the recipient is authorized to communicate directly to the integration endpoint, then the integration endpoint will respond with the latest data for the request.API Gateway can be used to create an API to connect to Lambda functions - that is when the api is invoked, the Lambda function will be called.

The template to retrieve the headers and query string needs to be entered within the Integration Request section for the API page. serverless-api-gateway-caching. Intro.

In the second case you're describing, if the client doesn't send the header at all, or they send it with an empty/null value, you won't even see it in your Lambda function. API Gateway will throw this request back with a 401 immediately. In the case of an invalid token, you have two options: 1. serverless-api-gateway-caching. Intro. A plugin for the serverless framework which helps with configuring caching for API Gateway endpoints. Good to know. If you enable caching globally, it does NOT automatically enable caching for your endpoints - you have to be explicit about which endpoints should have caching enabled. In this case, the list of recipients are contained in the header 'myHeader'. And the same example in Java DSL: And with a slightly different syntax where you use the builder to the fullest (i.e. avoid using parameters but using stacked operations, notice that header is not a parameter but a stacked method call) The header must contain the value passed in query string parameter __amp_source_origin; Access-Control-Expose-Headers: AMP-Access-Control-Allow-Source-Origin. The sole purpose of this header is to allow AMP-Access-Control-Allow-Source-Origin to be set; Plus standard CORS headers: Access-Control-Allow-Credentials: true Nov 23, 2019 · Discusses the options for hosting an AWS Lambda function behind a custom domain name, such as reverse proxying, or configuring base path mappings in AWS API Gateway.

In our case, the idea is that the API gateway verifies the incoming Authorization header, even before the request gets proxied to our application. It should cache the result, so that if the same user requests five endpoints, we still only verify the token once per hour, and it should pass on the authentication info to our APIs, so that we know ... The ARN prefix to be used in an aws.lambda.Permission’s source_arn attribute or in an aws.iam.Policy to authorize access to the @connections API.
