> While the Spark UI shouldn't be publicly visible some folks do have browser pre-fetches, and especially agents may execute GET requests expecting them to be side-effect free. Because of how YARN's proxy works though we can't make all actions POST only when deployed on YARN so we'll need to make this property dynamic.
