# log_append
|
||
|
|
|
||
|
|
Appends a field to the access log for the current request.
|
||
|
|
|
||
|
|
This should be used alongside the [`log` directive](log) which is required to enable access logging in the first place.
|
||
|
|
|
||
|
|
The value may be a static string, or a [placeholder](/docs/caddyfile/concepts#placeholders) which will be replaced with the value of the placeholder at the time of the request.
|
||
|
|

|
|
## Syntax
|
||
|
|
|
||
|
|
```caddy-d
|
||
|
|
log_append [<matcher>] <key> <value>
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
Display in the logs the area of the site that the request is being served from, either `static` or `dynamic`:
|
||
|
|
|
||
|
|
```caddy
|
||
|
|
example.com {
|
||
|
|
log
|
||
|
|
|
||
|
|
handle /static* {
|
||
|
|
log_append area "static"
|
||
|
|
respond "Static response!"
|
||
|
|
}
|
||
|
|
|
||
|
|
handle {
|
||
|
|
log_append area "dynamic"
|
||
|
|
reverse_proxy localhost:9000
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
