bash while loop with mixed condition

I'm not meaning multiple conditions, well it's also but mixed from that:

while [[ read line ] && [ "$GoodURL" == "false" ]]

What is the correct form for that? It's a while loop that runs on a text file line by line, and I want to stop it with that $GoodURL type of boolean, please help. Thanks.

while read line && [[ "$GoodURL" == "false" ]]
do 
    echo $line; 
done

In case you want to read from a file/pipe, be sure to use indirection or you will get funny results (due the while loop executing in a subshell and not actually using the same environmen as the surrounding shell)

while read line && [[ "$GoodURL" == "false" ]]
do 
    echo $line; 
done < input.txt
