When I debug a Visual Studio project using Chrome the browser tries to redirect to the https equivalent of my web address. I do not have SSL enabled in the web project and the start URL is the http URL. When I debug using FireFox or IE I do not have this problem.
I did re-install Chrome which fixed the problem for a day. Without downloading any addons the problem happened again the next day.
What is making Chrome redirect localhost to https?
Network Inspect Shows: Request URL:data:text/html,chromewebdata Request Headers Provisional headers are shown User-Agent:Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.143 Safari/537.36
No preview and no response data in those tabs.
I believe this is caused by HSTS - see http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security
If you have (developed) any other localhost sites which send a HSTS header ...
e.g.
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
... then depending on the value of max-age
, future requests to localhost will be required to be served over HTTPS.
To get around this, I did the following.
chrome://net-internals/#hsts
This is not a permanent solution, but will at least get it working between projects. If anyone knows how to permanently exclude localhost from the HSTS list please let me know :)
Chrome has recently moved this setting to sit under the section
Delete domain security policies
If you are using .dev domain see other answers below as Chrome (and others) force HTTPS via preloaded HSTS.
