browser caching static files in flask?

Question

Have been reading flask docs in python and building a local website.

Just performed a speed test on my website deployed on openshift with this tool here:-

The analysis report says that my site is not caching static resources. After googling this for all my worth I gather that:-

• It has something to do with headers.
• Cache copies are kept in the client machine and also servers between the client and website.

My Question

• Am I to include expire and tags in the html section? Or in the HTTP header section?

• If in the HTTP header section how do I do this?

If I have missed something in the docs please let me know.

Either use 'SEND_FILE_MAX_AGE_DEFAULT' or look into webassests http://webassets.readthedocs.org/en/latest/
