I'm building a web app. All the external links worked in my Project directory worked fine before but I noticed that yesterday every time I modify the .css file it didn't render this change at all. It actually is freezed with the same style regardless if I even erase the whole .css file content.

This is the response that I'm getting when I run flask:

 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger pin code: 230-950-485
127.0.0.1 - - [09/Mar/2017 17:53:09] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [09/Mar/2017 17:53:10] "GET /static/css/main.css HTTP/1.1" 200 -
127.0.0.1 - - [09/Mar/2017 17:53:10] "GET /static/js/main.js HTTP/1.1" 200 -
127.0.0.1 - - [09/Mar/2017 17:53:10] "GET /static/css/main.css HTTP/1.1" 304 -
127.0.0.1 - - [09/Mar/2017 17:53:14] "GET /favicon.ico HTTP/1.1" 404 -
127.0.0.1 - - [09/Mar/2017 17:54:04] "GET / HTTP/1.1" 200 -

Notice the 304, seems like that might be the problem? I appreciate any advice in what steps to take.

In Flask this is very common, whether you use Internal or external files:

HTTP Response

304 NOT MODIFIED

A conditional GET or HEAD request has been received and would have resulted in a 200 OK response if it were not for the fact that the condition evaluated to false.

In other words, there is no need for the server to transfer a representation of the target resource because the request indicates that the client, which made the request conditional, already has a valid representation; the server is therefore redirecting the client to make use of that stored representation as if it were the payload of a 200 OK response.

This means Flask is telling the browser that it already has the content.

If you clear your browser cache and you will notice that Flask returns a 200 on your next request.

Disabling cash solutions for this issue is not working for me. If it doesn't update the file because it already represented, it means if i have new code in my file, i will never be able to push these modifications

304 means you have compiled that file before and there are no modifications to the file. You can clear them by deleting cache file on pycache folder
