uwsgi-router-isfreshfile

Gives you an extra router condition by which you can check if a given file is to be considered "fresh" or if it is outdated. The check is done against the file's last modified timestamp.

Usage

route-if = isfreshfile:<path-to-file>,<age> other-action:...

You need to include the path to the full file you wish to check for freshness and provide the maximum allowed age in seconds.

Flat file caching with expiration

This plugin is part of a set of tiny plugins which aims to give the user flat file caching with sane directory structure and file expiration.

Other plugins in this set:

• uWSGI mkdir

With the above plugin you can create a directory structure based on any available variable.

Complete usage example:

# Check if the cached file is fresh (86400 = 24 hours), if so serve it directly.
route-if = isfreshfile:/tmp/uwsgi_cache${PATH_INFO}file.html,86400 static:/tmp/uwsgi_cache${PATH_INFO}file.html
# Not fresh or does not exist? Create the full directory structure first.
route = .* mkdir:/tmp/uwsgi_cache${PATH_INFO}
# And (re)create the cached response file.
route-run = tofile:filename=/tmp/uwsgi_cache${PATH_INFO}file.html
