Cache

Features

• The plugins add support for altering cache information on the response

Configuration

You need to enable the plugin by adding the element.plugins.cache module and defines a set of cache_control entries.

element.plugins.cache:
    cache_control:
        - { "path": "^.*\\.(txt|jpg|png|gif|xls|doc|docx)$",    "Cache-Control": ['public', 's-maxage=14212800']}
        - { "path": "^(blog|gallery).*",    "Cache-Control": ['public', 's-maxage=3600']}
        - { "path": "^.*\\.rss",            "Cache-Control": ['public', 's-maxage=3600']}
        - { "path": "^contact.*",           "Cache-Control": ['private', 'must-revalidate']}
        - { "path": "^/$",                  "Cache-Control": ['public', 's-maxage=3600']}

A cache entry defines:

• path: a regular expression to find the rule that should be applied.
• Cache-Control: the data to append to the response

By default, if no match is found then the Cache-Control value will be private, must-revalidate

Architecture

• The plugin listen to the element.node.render_response event.
