Added warning logs when HTTP/1.x request/response parsing fails
to aid in debugging malformed traffic and parser issues.
Changes:
- Log warning when ParseHTTP1Response returns nil
- Log warning when ParseHTTP1Request returns nil (SSL events)
- Log warning when ParseHTTP1Request returns nil (plain HTTP)
Includes src IP and data length for context.
