Why is this file not cached in the browser? What's wrong with my headers?

Asked 2021-Jun-10 at 20:26

I'm using Cloudfront (with Cloudflare in front) to serve the following file:

These are the response header at the time of writing:

Browser caching is determined by the caching headers (namely Cache-Control or Expires) in the response from the origin server. But the response you listed doesn't have such a header, so it's up to the browser to determine how long the resource is considered fresh.

If you want the browser to use a particular cache policy you should add a Cache-Control header to the response.

Due to the grouping you already have, count($elems) will have the right value in the return clause.

I think you original use of the let $sep is causing problems, the grouping count($elems) I suggested works fine for me at https://xqueryfiddle.liberty-development.net/bFDbxm7 where I have moved the $sep to a declared variable.

QUESTION

Centralized Logging architecture in AWS with X-Ray

Asked 2021-Jun-07 at 16:26

I am new in AWS and need a Centralized Logging architecture with X-Ray. For this issue, I checked the AWS reference implementation: https://docs.aws.amazon.com/solutions/latest/centralized-logging/architecture.html which shows an interesting architecture.

My question is, how and where I should use X-Ray in such an architecture? My goal is to have a centralized account, which will be aware, about the underlying services, especially from other accounts.

Thanks.

...

ANSWER

Answered 2021-Jun-07 at 16:26

AWS X-Ray is a distributed tracing service and not a logging service. Hence it doesn't fit into the above architecture. But if you still want to use X-Ray and have traces sent to a single common account, there's a way to do so using X-Ray daemon. If you are managing the X-Ray Daemon on your own, you can provide an IAM role of your central account which the daemon would use to send all the traces to. Docs for daemon configuration: https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon-configuration.html

Please keep in mind that services like API Gateway and Lambda have a self-managed daemon and currently only send traces to their own account.

I just received a helpful answer to a question about xml->tabular transformation, but I don't understand how to apply it to a document where an element may have several child nodes with the same tag.

As a minimal example, consider the books.xml file at the W3Schools web site.

I'm trying to instantiate blocks like Minecraft with a Raycast. It works, but if I click a block with a different rotation to (0,0,0), my block spawn in the same position of the block that I clicked.

Never directly compare float values using ==. Due to floating point precision something like 5 * 0.2f / 10f might be 0.99999999 or 1.0000000001 so a check for == 1f would fail!

Therefore you would always rather check if it lies within a certain range like e.g.

Having separate arrays for each tab(comedy and horror) worked for me, so you just create a second array and duplicate the javascript functions, using more specific JS selectors.
