I want to import the plain text and assign it to the variable. I am doing it in the Wolfram Programming Cloud

LesMiserables = Import["http://www.gutenberg.org/cache/epub/135/pg135.txt"];

When I press shift+enter, the output is as follows

The request to URL http://www.gutenberg.org/cache/epub/135/pg135.txt was not successful. The server returned the HTTP 
status code 403 ("Forbidden")

I have tried importing the text from other websites but the error is always the same, so I assume there is not problem with the website, but with the code(cloud).

Could anyone help?
