Reference to files in conversation

Normalizing User-Agent (UA) strings is a smart move. Raw UA strings are messy, inconsistent, and can be easily spoofed, but they provide a vital "fingerprint" layer when combined with IP and Session IDs.

For a high-traffic site like a video host, storing raw strings leads to database bloat and slow queries. Here is how to normalize them effectively for bot detection and rate limiting.

1. The Multi-Layered Normalization Approach

Don't just store one version of the UA. I recommend breaking it down into three distinct database columns to balance storage efficiency with query flexibility.
