Directing requests to instance on Google Cloud

Is it possible to group certain requests togeather based on their url ensuring that similar requests go to the same instance?

E.g. There are multiple instances for my app engine

myurl.com?foo=abc // Multiple people putting in this url will all go to the same instance

myurl.com // I don't care which one this goes

I don't think you can control which instance handles a url pattern.

If you want to send certain urls to a certain service, what you want is a dispatch.yaml, which does exactly that. You can use regex to tailor how you want. With some strategy, you could match urls with (groups of) instances, though they would be in separate services. If your site doesn't get a lot of traffic, you could essentially have one instance per service, and accomplish what you want.

dispatch:
# don't forget: gcloud app deploy dispatch.yaml   after changes !!!

- url: "*/some/high/memory/urls/*"  
  service: my_high_memory_service

- url: "*/some/fast/cpu/url"  
  service: my_fast_cpu_service
  
- url: "*/.*"
  service: default
