apache logging httpd

I keep running into I'm testing a new approach and I'm trying to configure Apache 2.4.54 to conditionally log requests based on a custom request header, but it seems my setup isn't working as expected. I want to log requests only when the custom header `X-Track-Request` is present and set to `true`. I tried using the `SetEnvIf` directive to create a condition for this, but my logs don't seem to reflect this filtering. Here’s the code I added to my `httpd.conf`: ```apache SetEnvIf X-Track-Request true track_request CustomLog logs/conditional.log common env=track_request ``` However, when I check the `conditional.log`, it still logs every request, regardless of whether the header is present. I also verified that the header is being sent correctly in my requests. To troubleshoot, I added some debugging with `LogLevel` set to `debug`, but the logs don't indicate any issues with the environment variable being set. I also confirmed that the requests include the header by using `curl`: ```bash curl -H 'X-Track-Request: true' http://mydomain.com/api/test ``` I've also attempted to simplify the `CustomLog` directive to make sure there's no syntax scenario, but it hasn’t resolved the question. I’m not sure if there’s a conflict with other logging configurations or if I'm missing something in my approach to using `SetEnvIf`. Any guidance on how I can ensure that only requests with this specific header get logged would be greatly appreciated! The stack includes Apache and several other technologies. Is there a simpler solution I'm overlooking? Cheers for any assistance!
