Tag: Browser limits

According to the RFC 6265 specification, browsers are required to support a minimum of 4096 bytes per cookie and 20 cookies per unique domain. This means that contrary to popular belief, there is indeed a limit to cookies, a fact with significant implications for web developers and marketers alike. Understanding these browser-enforced constraints is crucial for ensuring website functionality and performance.

Browser standards, specifically RFC 6265, dictate a maximum recommended cookie size of 4096 bytes, or 4KB. So, is 400 too high for cookies? No, a 400-byte cookie is well within this technical limit, but understanding how cookie size impacts performance is critical for developers and website owners.
