Preserve anchors in path destination parameter

[alisonjo315]

Go here:
https://fcs.cornell.edu/projects/design-standards-details/design-standards-details#test

Note that the login button URL destination parameters do not have #test in them. (If you feel like it, go through the motions: use the login buttons to log in -- you'll find yourself on the correct page, but without the #test anchor.)

Research Services requested to have the anchor link preserved in login links like these, and I agree, that'd be great!

• For Research Services, it was a JS solution -- IIRC it has to be JS b/c the server is unaware of anchors/fragments --

Dang, so far what I'm reading on The Internet is that the # part of the URL is never sent to the server, so we can't access it with PHP / it's not available when you GET your current path, via PHP.

(I went part-way down a "Symfony things with the word Fragment in them" rabbit hole (just by typing random things into my IDE to see if there were suggestions that seemed promising -- FragmentListener sounded so nice!!) but I managed to stop so I can ask fancy PHP devs before proceeding.)

So, fancy PHP devs: Does what I'm saying sound right to y'all, or no? (I hope not, I hope I'm missing / misunderstanding something!)

(If my "findings" are accurate, I guess I might have to pursue a JavaScript solution, for the customer request I'm handling right now -- but, hopefully I'm missing/misunderstanding something 🤞)

Thing is, even if you go directly to a static/hard-coded link like this, simplesamlphp makes you lose the anchor link anyway -- probably because the fragment isn't sent to the server, and simplesamlphp can't do anything about it any more than I can...
