Incorrect SCRIPT_NAME with apache ProxyPassMatch when a plus '+' is in path #12996

Description

do you remember:
#10869

I copied the title.. and replaced the 'space' with a 'plus' ( + ).

I had the same naging problem in my NextCloud instance when spaces were in file names the whole darn thing went the way of the dino..

And I thought of a "Q&D" way to get around that bug.. which turned out to NOT be a NextCloud bug, but a PHP 8.1 bug..

After updating PHP to 8.1.18 my "Q&D fix" wasn't needed anymore and I removed that piece of code..

If only I kept it in.. as it turns out an other (less often occurring) bug became more and more irritating.. the 'plus sign'

I have searched in all kinds of directions.. never thinking of the "space bug".. but there was the solution (one I wrote myself..)

Long story short: could you implement a "version 2" fix of the "space bug" for the "plus bug" ?
