# Forked from https://github.com/elasticsearch/logstash/tree/v1.4.0/patterns
## These patterns were tested w/ haproxy-1.4.15

## Documentation of the haproxy log formats can be found at the following links:
## http://code.google.com/p/haproxy-docs/wiki/HTTPLogFormat
## http://code.google.com/p/haproxy-docs/wiki/TCPLogFormat

# Example:
#  These haproxy config lines will add data to the logs that are captured
#  by the patterns below. Place them in your custom patterns directory to
#  override the defaults.
#
#  capture request header Host len 40
#  capture request header X-Forwarded-For len 50
#  capture request header Accept-Language len 50
#  capture request header Referer len 200
#  capture request header User-Agent len 200
#
#  capture response header Content-Type len 30
#  capture response header Content-Encoding len 10
#  capture response header Cache-Control len 200
#  capture response header Last-Modified len 200
