Hey Stackoverflow people,
In lighttpd, I want to set specific HTTP headers for a specific file (not site wide).
Basically I don't want to cache the main index.html file.
One catch, I can't add any new modules to lighttpd.
You can't add new modules, but have not shared which modules are available in your limited environment. This is not a well written question.
If you are unable to use mod_expire in lighttpd, then I would suggest using meta http-equiv tags in the index.html to limit caching.
