Question

I noticed that Chrome doesn’t seem to make an HTTP request to docs.google.com under some circumstances.

What I did, while capturing traffic using Wireshark:

• Visit Google Docs, log in
• Close Tab
• Clear cache (Cache and hosted apps)
• Visit http://docs.google.com/

I cannot find a single HTTP request to docs.google.com, all I see is SSL traffic.

I know that there are technologies like SPDY, Cache manifests and DNS CNAMEs that could interfere, but none comes to my mind that could really make the request disappear, especially after clearing the cache.

Answer 1

All requests to http://docs.google.com immediately redirect to https://docs.google.com/. This is hardcoded in Chrome and called HSTS.
