Rejoice! If the subject does come up again (as opposed to how it’s used now which is essentially named pipes for IPC but in HTTP form) just know there are TLS approaches that can be taken.
Now the next step is to remove the unnecessary base64’ing (HTTP is a byte-based protocol, not a text based one). Then finally, make sure the benefits of HTTP streaming are used (e.g. if I download a 1G file over the launcher, it isn’t loading it all in memory or something). I mentioned another couple of things at Safe Launcher Dev Issues/Suggestions but in general this is a great improvement for performance and idiomatic HTTP usage. Thanks!
