dev.sec-cors-preflight Calculator
Calculates CORS preflight request overhead and cache effectiveness from preflight TTL settings in a security engineering and compliance context. CORS preflight OPTIONS requests add a round trip before every non-simple cross-origin request — Access-Control-Max-Age caches the preflight result for up to 24 hours.
Inputs
Rps
Reference formula or conversion factor shown for context.
Maxage
Age in completed years. Many health and fitness formulas adjust for age.
Pct
Reference formula or conversion factor shown for context.
Results
preflight req/s
CORS preflight OPTIONS requests per second. High preflight rate can be reduced with longer Access-Control-Max-Age cache headers.
saved with cache
The total amount saved compared to the baseline scenario — cost savings, time savings, or resource savings.
remaining preflights
Sample size or count used in the calculation.
daily requests
Reference formula or conversion factor shown for context.
grade
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
