By default, FlyingPress does not cache URLs with query parameters. These are bypassed to avoid caching unnecessary or duplicate content.
However, if a query parameter changes the visible content, you can tell FlyingPress to treat it as unique and generate a separate cached version.
How it works
Once you add a query parameter to this setting:
FlyingPress will cache URLs with that parameter separately.
Each variation will get its own cached HTML file.
Example:
/products/→ cached/products/?filter=red→ bypassed by defaultAdd
filter→/products/?filter=redis now cached separately
When to use it
Use this only when the parameter actually changes the page content.
Examples (safe to cache):
/products/?filter=red— filtered product list/blog/?page=2— paginated content/deals/?sort=price— sorted listings
Avoid caching:
Tracking or marketing params (
utm_source,fbclid,ref)Temporary/session-based values
FlyingPress already ignores many common tracking parameters automatically.
