Content type cache

Pages with non-default content types (raw mode, api mode, or custom content_type:) store the content type in a sidecar cache file so that cache hits can serve the correct Content-type header without re-reading the source.

Storage location

public_html/lazysite/cache/ct/

Filename format

Path separators are replaced with colons. For example, api/status becomes api:status.ct. The file contains only the content type string.

When written

A .ct file is written when the page's content type is not the default text/html; charset=utf-8. This applies to:

• api: true pages (default: application/json; charset=utf-8)
• raw: true pages (default: text/plain; charset=utf-8)
• Pages with explicit content_type: in front matter

When read

On cache hits (the fast path in main()), the .ct file is read to determine the correct Content-type header. If no .ct file exists, the default text/html; charset=utf-8 is used.

Cleanup

When a page is rendered and its content type is the default (or undefined), any existing .ct file for that path is deleted. This handles the case where a page changes from api: true back to normal mode.

Example

$ cat public_html/lazysite/cache/ct/api:status.ct
application/json; charset=utf-8

Notes

• Normal HTML pages never write a .ct file
• The cache directory is created automatically on first write
• To clear all content type cache entries: rm -rf public_html/lazysite/cache/ct/
• API mode - pages that use non-default content types
• Raw mode - another mode with custom content types
