[C-Entropy]

when visit / (using with weblocks), you will see the following error from your repl:

There was an error processing your request: The value
                                              NIL
                                            is not of type
                                              SIMPLE-STRING
                                            when binding STRING

for more info. It turned out because quri returns NIL when recive something like 127.0.0.1:1080. see here
