Browser Caching wont auto clear, the *.md file is still oldest until refresh page by hand

[fankes]

Bug Report

Steps to reproduce

Whether debugging locally or publishing to a github page *.md documents automatically generated md files are always cached and need to be manually refreshed on each page to get the latest *.md documents.

I tried the following method but it still doesn't work

 window.$docsify = {
        requestHeaders: {
            'Cache': 'no-cache',
            'Cache-Control': 'no-cache, must-revalidate',
            'Pragma': 'no-cache',
            'Expires': '0',
            'If-Modified-Since': 'Thu, 01 Jun 1970 00:00:00 GMT'
        }
}

Two issues with the same problem: #1119 #937

↑ Tried the solution but still doesn't work.

What is current behaviour

The document does not automatically refresh when the page is closed and reopened, requiring the user to manually refresh (this will cause confusion for users reading the document with old versions)

What is the expected behaviour

Get the latest version of *.md files in real time
