Curl command without using cache

Posted by: admin November 30, 2017 Leave a comment

Questions:

Is there a way to tell curl command not to use server’s side cache?
e.g; I have this curl command:

curl -v www.example.com

how can I ask curl to send a fresh request to not use the cache?

Note: I am looking for an executable command in the terminal.

I know this is an older question, but I wanted to post an answer for users with the same question:

curl -H 'Cache-Control: no-cache' http://www.example.com

This curl command servers in its header request to return non-cached data from the web server.

Answers:

The -H 'Cache-Control: no-cache' argument is not guaranteed to work because the remote server or any proxy layers in between can ignore it. If it doesn’t work, you can do it the old-fashioned way, by adding a unique querystring parameter. Usually, the servers/proxies will think it’s a unique URL and not use the cache.

curl 'http://www.example.com?foo123'

You have to use a different querystring value every time, though. Otherwise, the server/proxies will match the cache again.
