Your URL actually does return '13' for me with Zinc following the redirect:

So the question is why doesn't it work for you ?

Which version of Pharo and/or Zinc are you using ?

Are you behind a proxy ?

Hello,

Google Apps Scripts allows me to create a webapp function that returns json.  For security reasons the url to call the function returns a redirection. For example

Curl https://script.google.com/macros/s/AKfycbyjVyXa9cYqYZg6kfSdiT8l6S0Q3LEzn6FvonoI1G1MzXeegrOB/exec

Returns an html page with the redirection information, whereas 

curl -L https://script.google.com/macros/s/AKfycbyjVyXa9cYqYZg6kfSdiT8l6S0Q3LEzn6FvonoI1G1MzXeegrOB/exec

Returns the json value  (currently 13)

I tried to use ZnClient to do the same thing, and I thought that ZnClient automatically followed redirections, but when I inspect the value it seems to actually return a larger html page, rather than the json.  My Pharo code is:

(ZnClient new) get: 'https://script.google.com/macros/s/AKfycbyjVyXa9cYqYZg6kfSdiT8l6S0Q3LEzn6FvonoI1G1MzXeegrOB/exec'.

Do I have to set any other options?

Please Note: this is my first experiment with Google App Scripts, so it is very likely that the problem is with my script, rather than Pharo. However, the script does seem to be returning the correct value in the browser, so it might be some interaction between the two.

Cheers
Andy
