HAProxy - Load balancer
66255f7bbf
This patch adds support for extracting captured header fields to halog. A field
can be extracted by passing the `-hdr <block>:<field>` output filter.
Both `<block>` and `<field>` are 1-indexed.
`<block>` refers to the index of the brace-delimited list of headers. If both
request and response headers are captured, then request headers are referenced
by `<block> = 1`, response headers are `2`. If only one direction is captured,
there will only be a single block `1`.
`<field>` refers to a single field within the selected block.
The output will contain one line, possibly empty, per log line processed.
Passing a non-existent `<block>` or `<field>` will result in an empty line.
Example:
capture request header a len 50
capture request header b len 50
capture request header c len 50
capture response header d len 50
capture response header e len 50
capture response header f len 50
`-srv 1:1` will extract request header `a`
`-srv 1:2` will extract request header `b`
`-srv 1:3` will extract request header `c`
`-srv 2:3` will extract response header `f`
This resolves GitHub issue #1146.
