So I have an existing angular 7 web application (let's call this myapp) which runs on IIS (App Service) hosted in Azure.
There is a legacy application (let's call this theirapp), with it's own embedded browser, which will load our application by navigating to myapp's url.
When theirapp loads myapp, theirapp passes some information in the header something like Request.headers.SpecificThingMyAppNeeds
I need to be able to access this request.headers in myapp.
Thank you all!
