Does Android or iOS handle common web HTTP headers like web browsers?

I've made a web app that employ "session cookie" to handle authentication ,"json" for interchanging between browser and server. ,"Cache-Control" header as cache mechanism , "Location" header for some redirection,"Content-security-Policy" for security reasons and some other HTTP specs;

Know i want to make an Android app for this web app with the same functionality that would uses the same content (the same URLs for fetching json-data and images and so on).

Do I need to implement client-side of the features mentioned above in android by myself or they are already implemented by android networking libraries??!! Did i get the right way(to using the same URLs for android)??!!
