How to send cache-control: no-cache from mobile?
Question
we're using Varnish for caching our pages, and it is configured to differentiate user-agent versions of pages. So mobiles will have different version of page than desktop browser.
From a desktop browser, it's easy to send a "cache-control: no-cache" with CTRL+F5 shortcut. It will enforce Varnish to refresh the page in its cache.
But how to do the same thing from a mobile, how do not have any CTRL key ??
Many thanks Etienne

As i know, just three options available on different browsers:
- Slide down
- Settings -> Refresh
- Settings -> Privacy -> Clear cache (All/For this site only)
If 1 and 2 doesn't help you just make extra click to clear cache manually
UPDATE: Ok I check safari and chrome at this site : it seems like you cannot send pragma: no-cache , from browser, only programmatically via meta tags, so there is no way to do it

The only solution I found :
- Install App "Rest Client For Android"
- paste the URL
- add custom HTTP header "Cache-control: no-cache"
In the response, Varnish (depends on your config) add an http header who says "missed" = response doesn't come from the cache.
