301 redirect in mappingFallback Action

Hi vuestorefront fans,

i’m working on using the url rewrite function in Magento 1. I’m extending the mappingfallback Store Action and getting the rewritten Url Path from Magento but now i’m stuck and couldn’t find a lot of info on this subject.
How can i create a 301 rewrite on SSR in that store action function. I can see an example for page-not-found page in the asyncData function using a context object. But how to access this SSR context Object in this extended store action?

Thanks a lot
