Sending an HTTP request from iRule without delaying client requests

If you just need to send the data and don’t care about the response, you might be able to bend High-Speed Logging (HSL) to fit your needs.

I haven’t personally tried this, so take it with a grain of salt, but here’s what I would try:

1. Use an iRule to extract the data and send it via HSL (non-blocking).
2. Set up a lightweight external service (something simple in Python, Go, or Node) to receive the HSL logs.
3. Have that service forward the data to your HTTPS endpoint.

This keeps the iRule fast and non-blocking since the F5/iRule doesn’t have to wait on external HTTPS calls.
