Rate Limit ignored when endpoint is cached in FastAPI.

Rate Limit ignored when endpoint is cached in FastAPI.

In this simple example the limiter is completely ignored when I tested.

from fastapi_cache.decorator import cache

@router.get(
    "/api/v1/templates/{template_type}/{version}",
    response_class=MarkdownResponse,
)
@cache(expire=300)  # Cache for 300 seconds
@limiter.limit("15/minute")
async def get_template(
    template_type: str,
    version: str,
    request: Request,
    current_principle: dict[str, str] = Depends(get_current_active_principle),
):
    print("Fetching template:", template_type, version)
    ...

Hi @Amourspirit just a simple question, have you tried swapping the decorators, ie instead of:

@cache(expire=300)  # Cache for 300 seconds
@limiter.limit("15/minute")

use:

@limiter.limit("15/minute")
@cache(expire=300)  # Cache for 300 seconds

Does it fix your problem?
