The above is my HTML code.I have used url_for for rendering the template with css.
from flask import Flask,render_template
app = Flask(__name__)
@app.route('/')
def hello_world():
return render_template('Arcade.html')
if __name__ == '__main__':
app.debug = True
app.run()
app.run(debug = True)
The above is my python flask code. When i tried to run the code i got 304 erroe.So i cleared my browser cache and tried to rehost the application. But still the url_for couldn't grab the css and js files properly. No matter how many times i clear the cache and try I couldn't get the expected result.Please look into it and help me. Note: I have properly created a static folder and saved the css and js files in a separate folders namely JS and CSS.
Solution 1:[1]
You are receiving this error because the cached version of the requested file is the same as the file to be sent.
Fix it by:
Clear the Chrome's Cache Data.- It is possible that a
Computer Malwaremight be causing that problem, sorun a Malware Scan.- As a precautionary step, I'd suggest you also
disable any extensionsyou have installed on your browser.
- As a precautionary step, I'd suggest you also
Other Potential Problems
If it hasn't been solved by any of the methods above, it might be a DNS issue.
- Go to DNS settings
- Click
clear host cache
