caching - https over http - Does it mean downloading more MBs? -
when page static image files downloaded via https/ssl
protocol, browser caches them in encrypted form.
when browser starts next session server, ssl
encryption key changes , browser can no longer decrypt cached resource in next key. mean https
, static resources downloaded either cdn or remote web server. particulary, cases when http-headers expires/cache-control
have been set?
the data in cache not encrypted, , can reused between sessions. see example http://blogs.msdn.com/b/ieinternals/archive/2010/04/21/internet-explorer-may-bypass-cache-for-cross-domain-https-content.aspx explicitly says closing browser , contacting same page again result in cache hits.
