Website refresh issues #762
I couldn't reproduce the issue today, because it's random, however I think I solved it with this commit: 8163d63
The issue is we are modifying iframes, and kestrel sets the last-modified header based on the index.html file modification, thus I think sometimes some browser just assumes it wasn't modified based on the last-modified header field and returns cached resource. I set the last modified header field to the time of the request, so if this was the issue it's solved.
