When you are in the development stage it's a bit embarrassing to constantly remind your clients to clear the cache or to ask them to "refresh the page a bunch of times."
Is there a setting that I, the developer, can set in nginx or as a meta tag in the HTML to force all browsers to stop caching my page?
Theoretically, according to Difference between Pragma and Cache-control headers? and also http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32, the following may be sufficient, in nginx:
add_header Cache-Control no-cache;
In practice, you might have to specify some extra directives; it would seem like using the expires directive should be sufficient, which will automatically add the Cache-Control header as above, too:
expires -1;
