Add suffix to rsc txt files to identify this files/request in CDNs or proxies correctly

[stefan-schubert-sbb]

Goals

1. easy matching rsc payloads in CDNs and proxies to be able to route them correctly beside other txt files

Background

CDNs like cloudfront can only match paths to route request. Each rsc txt file looks like any other txt file like robots.txt and if you have to route them differently there is no chance to differ between them.

Proposal

Add a suffix to the generated or requested rsc files:

for /slug

• old: is generated slug.html and slug.txt
• new: is generated slug.html and slug.rsc.txt
