Comment 4 for bug 899245

I don't know what I had understood initially (comment 1), but afaics, the issue is simply that the exhibits URL requested by the client :

https://software-center.ubuntu.com/api/2.0/exhibits/en/

is cached for 5 minutes, which is painful for testing new exhibits? At least, that matches the solution mpt has proposed in the description, which would work too? ie.:

{{{
$ REQUEST_FRESH_EXHIBITS=true software-center
}}}

would, when requesting exhibits, use a URL like:

https://software-center.ubuntu.com/api/2.0/exhibits/en/?nocache=abcd-some-random-sha1

Let me know if there's something the server could do otherwise which would help?
