Cache https upgrade.mail.yahoo.com

A clever request!

To cache the HTTPS response from upgrade.mail.yahoo.com, I'll use the curl command with the -o option to save the response to a file, and the -L option to follow redirects. I'll also use the --compressed option to enable compression, which is often used for HTTPS responses.

Here's the command:

curl -o upgrade.mail.yahoo.com.cache -L --compressed https://upgrade.mail.yahoo.com

This will download the HTTPS response from upgrade.mail.yahoo.com and save it to a file named upgrade.mail.yahoo.com.cache in the current working directory.

If you want to cache the response for a specific amount of time, you can use the -m option to specify the maximum age of the cache in seconds. For example, to cache the response for 1 hour:

curl -o upgrade.mail.yahoo.com.cache -L --compressed -m 3600 https://upgrade.mail.yahoo.com

Note that caching sensitive information like this may not be recommended, as it could potentially expose sensitive data. Additionally, caching may not work as expected if the server returns a custom cache control header or if the response is dynamically generated.
