Providing another example

Here's a request to github for the sourcecode of a java class

https://github.com/spring-cloud/spring-cloud-consul/blob/master/spring-cloud-consul-discovery/src/main/java/org/springframework/cloud/consul/serviceregistry/ConsulServiceRegistry.java

By appending this with "#L90" the web browser will make the same request, and then scroll to line 90 and highlight the code.

https://github.com/spring-cloud/spring-cloud-consul/blob/master/spring-cloud-consul-discovery/src/main/java/org/springframework/cloud/consul/serviceregistry/ConsulServiceRegistry.java#L90

Your web browser made the same request to the github server, but in the anchored case, performed the additional action of highlighting the selected line after the response was received.
