Small Issue : efficient URI formation

[Shay2Shay]

suppose:

base = https://xyz.com/
sql    = /sql/v1/

this setup throws error => https://xyz.com/:443/sql/v1/

base = https://xyz.com

saves the day => https://xyz.com:443/sql/v1/

Looks like '/' is not handled.
But in python counterpart its handled - link

It will be nice if its handled properly
