Edge - Versionless static file routing (optional)

[huntharo]

Motivations

• Shared .js files (e.g. for a menu) need to have a versionless path that can be embedded in many apps
• favicon.ico files can benefit from being versionless

To-Do

• Consider 302 routing to current version of file
• Consider rewriting request in Origin Request to point to current version of file and adding a header to the request that is part of the cache key (if possible) so the file can be served from edge if that version was already cached
