Option that tries to grab etag to check for new version instead of date

[Vityacv]

If I try to use Direct APK link, every time I refresh it, it gives me new "version" (timestamp). Maybe it's possible to try to use etag instead if server supports it?
You could check it with curl like this:
curl -I 'https://example.com/app.apk'
It could return sometihng like this

HTTP/2 200 
server: nginx
date: xxx
content-type: application/vnd.android.package-archive; charset=UTF-8
content-length: xxx
last-modified: xxx
etag: "33a64df551425fcc55e4d42a148795d9f25f89d4"
x-amz-request-id: xxx
cache: HIT

Thanks!

Could you give me a real link that has an etag I can use to test with?

Could try for example
curl -I https://telegram.org/dl/android/apk
It will return redirect url that you'll need to use for next query:
curl -I https://cdn4.cdn-telegram.org/file/Telegram.apk
which returns for me

HTTP/2 200 
server: nginx/1.18.0
content-disposition: attachment; filename="Telegram.apk"
accept-ranges: bytes
etag: "98302836a2bac183b01c0b10cbd4ef0a4494dd9e"
content-type: application/octet-stream
