How To Set Http Headers With Different Content Type

I have a webpage dynamically created via Python. Its purpose is to provide images, so the first line sets the content type: Content-Type: image/png I would like to set http header

Solution 1:

Cache-Control, Content-Type and the like are HTTP headers, not "html style headers". You can use them regardless of the content-type.

Solution 2:

import string, sys, math, osprint("Cache-Control: max-age=" + str(86400 * 3650) + ", public")
print("Content-Type: image/png")
print("\n")

That sets the resource to expire in ten years.
