How do I alter this form to:  refresh same page if url is not /~login? 

Edit; answer was:
Code: [Select]
location.replace({.if|{.match|*~login|%url%.}|{:document.referrer:}|{:"%encoded-folder%":}.})

I think we can pass current page (%encoded-folder%) through urlvar (/~login?redirect=%2Fsome%2Ffolder%2F)
Then redirect in /~login page with javascript etc.
Busy in school until late June, 2021.
Check out my template ;)

if you clicked on a login link, then after login it goes back to where you had clicked
if you clicked on a passworded folder, then after login it goes Into the expected folder

The compact version is caching-compatible so that you can go from/to cached content without confusing the login/logout buttons.
