ATS 9.2.3 and cache bypass with parent

Hi Please help me to understand how should bypass work with ats 9. It worked well with ats 7, but apparently something has changed that I didn't see in changelogs before upgrading to 9.2. We have a test url that is located on upstream that we query regularly to check if upstream storage is

RAM cache on NVMe

Hi We are currently using Nginx in front of ATS to store hot content on NVMe-s, but would like to drop it and only use ATS. ATS is using full SATA HDD-s to store its content (about 150TB per node) and ATS RAM cache is disabled entirely. >From reading ATS documentation, I only found how to enable

Hi, ATS 7.1.2, parent routing enabled. Everything goes through parent except one test url request that has very small response size (20 bytes). To calculate ATS cache byte hit ratio, I'm using following metrics: "proxy.node.http.user_agent_total_response_bytes": "363046018479",
