Acronyms
Acronyms, are used all the time and the author /presentor is usually convinced that everyone in the audience understands what they mean, but every once in a while you hear or read something that you are not sure of the meaning. We are all professionals, that do not want to look like we are the only one in the room who does not know. So after hearing a talk or reading an article we often find ourselves looking it up; this can become confusing because acronyms mean different things when we search outside our field. For example CE what does it mean? The letters "CE" are the abbreviation of French phrase "Conformité Européene" which literally means "European Conformity". In the dictionary you will probably find CE meaning Common Era or Christian Era. When looking for a more modern meaning, we will find it may mean Consumer Electronics. But here in our community, when someone writes CE, they mean Customer Edge. Here, you have, at your fingertips a list of acronyms, unconfused with other fields. Please let me know if I missed any acronyms so I can add them to our list.

A quick post on how F5 XC Health Checks are different from BIG-IP
F5 Distributed Cloud (F5 XC) HTTP Health Checks (HC) behave differently from the basic HTTP Health Check from the beloved BIG-IP platform that F5 is known for. Because of this difference, some of your testing and real-world experiences may be a little different. One issue you may encounter is the difference in TCP/HTTP connection handling. On BIG-IP, the HTTP HC sends a HTTP/0.9 style GET request. With HTTP/0.9, there is no persistent TCP session, and every check is a brand-new request. By default, in F5 XC, XC will send HTTP/1.1 requests with the default behaviour of Connection: keep-alive set. This may result in Health Checks continuing to work even though new client sessions may be blocked. If this isn't desired for your health checks, you can change to a single use style health check by adding the HTTP header: Connection: Close to your health check. Here's a table that shows the GET requests and responses between BIG-IP and XC. HTTP Requests BIG-IP Basic HTTP XC Basic HTTP Get Request Hypertext Transfer Protocol GET /\r\n \r\n [HTTP request 1/1] Hypertext Transfer Protocol GET / HTTP/1.1\r\n host: demo.com\r\n user-agent: Envoy/HC\r\n \r\n [Full request URI: http://demo.com/] [HTTP request 1/1] Response Hypertext Transfer Protocol HTTP/1.1 200 OK\r\n X-Frame-Options: ALLOW-FROM \r\n Content-Type: text/html; charset=utf-8\r\n Vary: Accept-Encoding\r\n Date: Tue, 21 Mar 2023 15:59:11 GMT\r\n Connection: close\r\n \r\n [HTTP response 1/1] [Time since request: 0.001904999 seconds] [Request in frame: 14] [Request URI: /] Hypertext Transfer Protocol HTTP/1.1 200 OK\r\n X-Frame-Options: ALLOW-FROM \r\n Content-Type: text/html; charset=utf-8\r\n Vary: Accept-Encoding\r\n Date: Tue, 21 Mar 2023 16:18:44 GMT\r\n Connection: keep-alive\r\n Keep-Alive: timeout=5\r\n Transfer-Encoding: chunked\r\n \r\n [HTTP response 1/1] [Time since request: 0.080959858 seconds] [Request in frame: 4] [Request URI: http://demo.com/] HTTP chunked response Here is the JSON payload to create your own Health Check with the Connection Close header set: { "metadata": { "name": "hc-http-connectionclose-200-302", "namespace": "shared", "labels": {}, "annotations": {}, "disable": false }, "spec": { "http_health_check": { "use_origin_server_name": {}, "path": "/", "use_http2": false, "headers": { "Connection": "Close" }, "request_headers_to_remove": [], "expected_status_codes": [ "200", "302" ] }, "timeout": 3, "interval": 15, "jitter": 0, "unhealthy_threshold": 1, "healthy_threshold": 3, "jitter_percent": 30 } } Thanks for reading and best of luck in your journey with F5 Distributed Cloud.
F5 XC | Rewrite Redirect functionality
Hi together, for the migration to F5 XC we need to change the location header for certain responses (301,302) to match the hostname of the XC instance. Is there currently a way to configure a rewrite redirect to an F5 XC virtual server? I also couldn't find a configuration option that allows response header manipulation. I am grateful for any hint. Update: i found a feature Request for that functionality: https://www.f5cloudideas.com/ideas/MESH-I-149 but if there are any other ideas pls share with me 🙂
