How can i distribute geospatial request?

You can edit application.properties file, if you want to add routing nodes.

like this.

geoserver-0.ribbon.client.NIWSServerListClassName=com.netflix.loadbalancer.ConfigurationBasedServerList

geoserver-1.ribbon.client.NIWSServerListClassName=com.netflix.loadbalancer.ConfigurationBasedServerList

This example routing nodes by x min(xm) geospatial parameter values on CRS EPSG:3857

For example,

xm > 14151299 ? geoserver-0 : geoserver-1

/geoserver
├─ /geoserver-0
└─ /geoserver-1
