@ -354,21 +354,19 @@ The default cookie name is an abbreviation of a sha1 (ex: `_1d52e`).
On subsequent requests, the client will be directed to the backend stored in the cookie if it is still healthy.
If not, a new backend will be assigned.
To activate sticky session:
```toml
[backends]
[backends.backend1]
# Enable sticky session
[backends.backend1.loadbalancer.stickiness]
```
To customize the cookie name:
```toml
[backends]
[backends.backend1]
[backends.backend1.loadbalancer.stickiness]
cookieName = "my_cookie"
# Customize the cookie name
#
# Optional
# Default: a sha1 (6 chars)
#
# cookieName = "my_cookie"
```
