Why not use eBPF instead? Then you could see all http requests from all processes at once, including ones that are already running. Plus you wouldn't need to bother with TLS at all, just hook on e.g. write(2).

Using uprobes to hook the SSL library, would it be possible to filter content by inspecting and modifying eg the decrypted HTTP response ?
