Regex Tester & Validator

Parses extended nginx access log lines, capturing the client IP, identity/user, timestamp, HTTP request line (method, URL, protocol), status code, body bytes sent, referer, request time, upstream response time, cache status, user agent, and forwarded-for plus additional quoted header fields. Optional numeric and string fields accept '-' as an empty value. Ideal for log analysis, monitoring pipelines, and metric extraction from nginx server logs in Python.
