| session data |

session := ZnClient new url: 'http://cloud-storage.com'.

"Login"
session path: '/login';
    formAt: 'email' put: 'jom';
    formAt: 'password' put: 'mypass';
    post.

"Get data"
data := session path: '/my-file'; get; contents.

"Check for new data every 60 secs for maximum 100 tries"
[
    100 timesRepeat: [
        | newData |
        (Delay forSeconds: 60) wait.
        newData := session path: '/my-file'; get; contents.
        (data ~= newData) ifTrue: [Transcript show: newData; cr]
    ]
] fork.

NB. Despite above example code you may want to consider trying If-Modified-Since method in ZnClient.
